This movie is not just pretentious twaddle. It is inept and exploitive pretentious twaddle, not even worth a “so bad it’s good” video rental.

The title comes from the idea, here attributed to “chaos theory,” that the flap of a butterfly’s wing can produce a typhoon half a world away. Ashton Kutcher, way out of whatever league he is capable of playing in, is Evan, a tortured soul who was given to blackouts as a child. Now in college, as his memories begin to come back, Evan regrets not having been able to save Kayleigh (Amy Smart), the girl he loved, from her abusive father. He realizes that he has inherited the gift of being able to go back in time and change the direction of events. But each time he goes back, he makes things worse.

This is an irresistibly intriguing notion — all of us have thought about what would happen if we could go back in time and make a different choice, and the idea has been explored in formats from fairy tales to EC Comics to Twilight Zone episodes. And just about all of them have had more imagination, insight, and even believability than this version. If I could go back in time, I’d try to talk myself out of deciding to watch this movie.

Evan gets to go back to the moment in which he agreed to take his clothes off for a child porn video made by Kayleigh’s father (Eric Stoltz). Instead of saying no or running away or calling the police, 7-year-old Evan’s second chance decision is to explain to Kayleigh’s father in the words of his adult persona that her father should not destroy her life. Somehow, this instantly persuades him to stop molesting her.

Then college-age Evan, back in the present but of course remembering the original reality, is all of a sudden transformed from cool guy with goth roommate to frat boy, with Kayleigh transformed from suicidal waitress to the sweetheart of Sigma Chi.

But oh-oh, when 7-year-old Evan’s compelling powers of persuasion showed Kayleigh’s father the error of his ways, he somehow forgot to include Kayleigh’s brother Tommy, who now, in scenario #2, as the recpient of all of the abuse in the family, is rather over-protective of his sister and apt to get angry at anyone who wants to be her boyfriend. Disaster ensues and Evan has to find a way to go back to another fork in the road to try to make things work out better.

Other scenarios present other problems, including several variations in Evan’s facial hair to help Kutcher and the audience remember which one is which, as we run through a Jerry Springer assortment of every possible form of hideous crime and abuse, including animal torture, child molestation, the death of an infant, prison rape, and drug addiction, all unforgiveably thrown in for shock value and none with any shred of dramatic legitimacy. And wherever he is, psychology teacher’s pet, half-hearted participant in fraternity hazing, confined to prison, or confined to a wheelchair, Kutcher’s acting is not up to the challenge of making even a nosebleed believable. The only thing in this movie that makes any sense is the revelation in the credits that the producer with the poor judgment to put Ashton Kutcher in this mess was…Ashton Kutcher.

Parents should know that the movie has extreme graphic violence. Characters are severely wounded and killed, including children. A character commits suicide and an animal is tortured and killed. Children are also molested (off-camera) and there are references to prison rape. The movie includes nudity and very explicit sexual references and situations, including bondage gear, prostitution, and references to multiple orgasms. Characters smoke (including children), drink, and use drugs (bong shown, character is an addict, cocaine mentioned). Characters use very strong language, including hate speech.

Families who see this movie should talk about moments when they could have made a different choice and how that would have affected the lives of others around them.

Families who are intrigued by this idea will enjoy many better variations on the theme including the original Bedazzled, Frequency, Back to the Future, Groundhog Day, and of course the classic It’s a Wonderful Life. They should also look at this famous butterfly effect story by Ray Bradbury.

Ford (Martin Henderson) comes back to town with a score to settle and a woman to win back, just like a cowboy in an old western. Only in this movie, instead of horses, there are motorcycles, very fast ones.

This movie is one percent dumb plot, 74 percent stunts, and 25 percent attitude, or, rather Hollywood’s idea of what passes for attitude. So, Ford is the kind of guy who wears a Ramones t-shirt and a leather jacket that proclaims “Carpe Diem” (sieze the day). He must be the movie’s hero because he and his pals are so photogenically ethnically diverse that they look like they just stepped out of a Benneton ad.

The woman (Monet Mazur) has Hollywood’s idea of a cool name: Shane, a cool profession: mechanic, and a cool way in a fight. And they all say faux-tough lines like “I know you said it wouldn’t be any fun if it was easy, but does it have to be that much fun?”

The action sequences are silly fun, especially a chase scene that has one motorcycle racing on top of a fast-moving train while another rides through the train cars in between the passengers and a chick fight on motorcyles between Shane and a multi-pierced Jaime Pressly. Ice Cube’s appearance is more presence than performance, and Henderson is all about the dimples. But Fredro Starr makes an impression as Ice Cube’s, well, Fredo equivalent, and Faison Love as a gang member and Adam Scott and Justina Machado as FBI agents hold our interest.

Parents should know that the movie has a lot of violence for a PG-13 including many crashes and explosions, shooting, punching, kicking, and strangulation. Characters are killed. Characters drink, smoke, and use strong language, including the n-word and other epithets. One character gives another the finger. Characters ride in reckless and extremely dangerous ways, often without helmets. The plot centers on drug dealing. There are some sexual references but nothing very explicit. The soft drink product placement is particularly intrusive.

Families who see this movie should talk about why Cary ran away and why he came back. What made Trey change his mind about Ford? Practical-minded families might want to talk about the liberties this movie takes with some of the laws of physics.

Families who enjoy this movie will enjoy the better Biker Boyz and The Fast and the Furious.

The animated television series “Teacher’s Pet” makes a fast, fresh, tuneful, and funny feature debut that will entertain its fans and amuse their families.

Spot (voice of Nathan Lane) is a highly intelligent and articulate dog who dreams of becoming a boy. But then he wakes up. All he can do is pretend to be a boy, disguising himself as “Scott” and going to school with Leonard, the boy he lives with.

Leonard and his mother take off for Florida so she can participate in a teacher of the year competition, and Spot follows them after he sees a television interview with Dr. Krank (voice of Kelsey Grammar), who says he can change animals into humans. So far, his experiments on swamp creatures have produced some bizarre mutants, including something that looks like an alligator crossed with a kangaroo. But Spot helps Krank make some adjustments and gets turned into a human. Unfortunately, since they forgot to figure in the effect of dog years, Spot becomes not a boy but a middle-aged man “with hairy knuckles and lower back pain.” After many complications and adventures, a lot of sly humor, and several deliciously witty songs, everything is happily resolved.

Kids will enjoy the wild characters, silly plot turns, bright colors, and vivid images. The animation style is distinctive and unusual. While it is apparently simple, even childlike, with basic shapes and bold colors, it is actually quite sophisticated, designed by award-winning artist Gary Baseman, whose illustrations have appeared in many magazines and whose serious work is in the collection of major museums.

Older kids and parents will appreciate the wisecracks and the self-aware pop culture references from the Jetsons to Disney movies (including Snow White, Lady and the Tramp, and Sleeping Beauty).

And everyone will enjoy the music. While most movies directed at the youngest children have almost interchangeable soundtracks filled with watered-down rock and hip-hop or syrupy jingles, “Teacher’s Pet” has first-rate Broadway quality songs, beautifully sung by Tony-winner Lane and an able supporting cast of voice talents. Witty (and vocabulary-building) lyrics rhyme “defiance” with “science,” “appliance,” and “giants” and “foe” with “status quo.” One song hilariously lists all of the states and another reminds us that even the small among us can be mighty.

Parents should know that there is a little bit of potty humor and some comic peril and violence. One of the characters has an eye that keeps popping out. Some children may be concerned because Leonard does not have a father and his mother shows some romantic interest in Scott.

Families who see this movie should talk about how we can help each other even when we have different dreams.

Families who enjoy this movie will also enjoy the television series, still available in reruns. They might like to take a look at some modern artists whose work may have inspired the style of this cartoon, like Wayne Thiebaud. And they will enjoy the popular game Cranium, also featuring Baseman’s design work. Families who listen to the “Teacher’s Pet” song at the end of the movie might enjoy hearing it sung by Doris Day in a romantic comedy of that name co-starring Clark Gable or Parker Posey singing it at an audition in the deliciously looney Waiting for Guffman (for mature audiences).

“The Fog of War: Eleven Lessons from the Life of Robert S. McNamara” is an intelligent documentary directed by Errol Morris and based upon an interview with Robert McNamara, who as Secretary of Defense for Presidents John F. Kennedy and Lyndon B. Johnson was for many the face of the war in Vietnam. Long seen as an energetic technocrat, blamed for increasing the body count in the brutal conflict, McNamara has reappeared in the news following his book “In Retrospect: The Tragedy and Lessons of Vietnam” (1995).

The documentary features footage of iconic figures including Franklin Delano Roosevelt, Woodrow Wilson, Curtis LeMay, John F. Kennedy, Fidel Castro and Nikita Khrushchev, as it marches its way from WWI –McNamara’s first memories—nearly to the present. Although filming started before 9/11, McNamara makes some prescient comments about our current engagements abroad.

The eleven lessons are:

1. Empathize with your enemy.

2. Rationality will not save us.

3. There’s something beyond one’s self.

4. Maximize efficiency.

5. Proportionality should be a guideline in war.

6. Get the data.

7. Belief and seeing are both often wrong.

8. Be prepared to re-examine your reasoning.

9. In order to do good you may have to engage in evil.

10. Never say never.

11. You can’t change human nature.

In “Fog of War”, Morris has made a very strong documentary that stops short of excellence. His interview style –to place the subject in another room from him and appear to the subject on a television screen—is not entirely effective with McNamara who is clearly comfortable in front of and with cameras. McNamara’s true moments of reflection seem fueled by his own thoughts from the intervening decades and not by Morris’ questions which he interprets to fit his answers. When Morris shouts questions, McNamara often shrugs them off as if they were impertinent or irrelevant, mere distractions from the internal dialogue he has with his own ghosts. What becomes apparent is that McNamara cannot clear the fog of war from his own eyes, much less from ours.

For those seeking to better understand the reclusive octogenarian, this film –while riveting—does not go beyond the line McNamara already drew in his book, which similarly contains a tone of semi-reporting, semi-excuse, semi-apology, stopping short of simple answers. Morris has done an excellent job of weaving footage and recordings together, complemented by Philip Glass’s score which is a narration in itself. We see more clearly what the decision makers said about the situation in Vietnam but the glimpses are neither incisive enough to answer our questions nor broad enough for us to question our answers. Morris cannot do the impossible task that he has created for himself, which is to help us see clearly in a time of war, but he can –and does—succeed admirably in presenting a good interview with an interesting and haunted man.

Parents should know that this movie touches on mature themes related to politics, protests and war. Allusion is made to fire bombs, nuclear weapons, Agent Orange and the effect of these weapons on the targeted populations. Self-immolation in protest of Vietnam and the near immolation of a protester’s child is discussed.

This movie provides rich content for family discussion, starting with the major issues McNamara raises in the interview. Who is responsible for US involvement in an extraterritorial conflict? Under the US political structure, what might be the checks and balances to prevent or guide US involvement in a time of war? How do perceptions of the mentioned military engagements, including WWI, WWII, Viet Nam, Iraq, differ and why?

“War is cruelty. There is no use trying to reform it. The crueler it is, the sooner it will be over.” Families might wish to discuss this sentiment, expressed here by General Sherman in the context of the Civil War, and how McNamara uses it to describe WWII bombings. Is there a developed sense of ethical behavior during a time of war? What “rules” might there be? If you can’t change human nature, what can you do to prevent war or ameliorate conflicts?

As described in the film, Congress placed the decision to wage war on Vietnam with the Executive Office, which some people argue means that they abrogated their responsibility. Should one person, in this case the President, be responsible for the decision to go to war? If you were in McNamara’s place as a close advisor to a president considering going to war, what would you have done? McNamara describes disagreeing with President Johnson on many aspects of the conflict in Vietnam and eventually leaving the administration. If you disagreed with the President, how would you address the problem? What other solutions would you consider? Would you resign?

Morris stops the interviews with discussions of Vietnam, but McNamara in his next job was responsible for re-shaping the World Bank to focus on poverty. McNamara argued that addressing inequality could prevent the causes of war. Do you think that there are other ways to prevent war?

Families who like this documentary might enjoy seeing Morris’ earlier works, including The Thin Blue Line about an innocent man imprisoned for murder, Fast, Cheap & Out of Control which is a poetic reflection on the obsessions of four men, and Gates of Heaven, the documentary about pet cemeteries that launched his career.

For families who wish to see a much different documentary with insights into ethics during a time of war, The Trial of Adolf Eichmann is a fascinating look at the man in charge of implementing the Third Reich’s horrific Endlosung (“final solution”). Other political documentaries about the U.S. that might be of interest include Point of Order, a mesmerizing snapshot of the last days of Senator Joe McCarthy’s hearings.

Pop princess Mandy Moore plays the President’s runaway 18-year-old daughter in this formula romantic comedy designed for middle school girls and not of much interest or appeal for anyone else.

Anna (Moore) is a sweet kid who understands that being followed by secret service agents and having her picture taken with tourists and dignitaries is part of the job decription. Like any other 18-year-old, she thinks her parents are too protective. Her secret service code name maybe “Liberty,” but she feels anything but free. On a trip to Prague, her father (Mark Harmon) breaks his promise to limit her secret service protection to two agents, so she runs away, with the help of a handsome guy named Ben (Matthew Goode) with all three requirements to make any pop princess swoon — a dazzling smile, a moped, and a British accent.

It turns out that Ben is in the secret service, too, but the President orders him not to tell Liberty, so that she can have the illusion of an adventure. Things do not go as planned, and they end up having more of an adventure than they expected.

The movie has pretty things to look at, especially Prague and Venice and newcomer Goode who is very good indeed. And we want to root for the overprotected Liberty, never alone but always lonely, to take some risks and have some fun. But Moore is so limited as a performer, the plot and dialogue are so superficial and unimaginative, and the lack of chemistry between the leads is so intrusive that a recap montage of the would-be high points near the end just seems painful.

Parents should know that characters use some strong language in the movie (about the level of night-time network television) and characters smoke (there is a running joke about the President liking cigars) and drink (while they make it clear that Liberty is not breaking the law because it is legal to drink at age 18 in Europe, she does get tipsy and behaves foolishly as as result). Characters also lie and steal without any second thoughts or consequences. Liberty and Ben leave a restaurant without paying and lie to get a free gondola ride.

The movie has sexual references that are much spicier than the sexual situations. A girl begins to explain the appeal of a pierced tongue, but is stopped before she can finish. Liberty complains about not getting a chance to get to “third base.” Liberty twice takes her clothes off in front of Ben (nothing shown), once intending to seduce him, but he refuses. Even after they declare their feelings for each other, they do not have sex, a refreshing departure for the norm in this genre.

Families who see this movie should talk about how Liberty’s situation is just an exaggerated version of the struggles that all parents and teenagers have over independence. Why did Liberty try to get Ben to have sex with her? Why did he turn her down? What made them like each other? Families might want to read up on Alice Roosevelt, the headstrong and outspoken daughter of President Theodore Roosevelt. When asked why he did not stop her from getting into trouble, he replied that he could control the affairs of state, or control Alice, but could not possibly do both.

Families who enjoy this movie will also enjoy two classics of the lonely, overprotected rich girl runaway genre, the multiple Oscar-winning It Happened One Night and Roman Holiday, must viewing for all families with young girls. Older viewers might enjoy another peek at romance in the White House with Michael Douglas and Annette Benning in An American President. A bittersweet story about the relationship between a President’s widow and a Secret Service agent is Guarding Tess. The script is not very imaginative, but the movie is worth watching for lovely performances by Shirley Maclaine and Nicolas Cage.
