On the one hand, this movie is a lazy, dumb, and misogynistic and it promotes pot smoking, unemployment, and burglary. On the other hand, it is genial and unpretentious. If it does not take drug use, crime, racism, and sexism too seriously, it does not take itself too seriously either. Almost every joke in the movie is taken from another movie, but the cast enjoys them so much that they occasionally make it work.

This is the sequel to “Friday,” a movie that performed modestly in theaters but became a hit on video. In the original, Craig (played by rap star Ice Cube, who co-wrote the screenplay) spent the day smoking pot and beat up the neighborhood bully. The sequel, again written by and starring Ice Cube, has the bully breaking out of prison and looking for revenge. Craig goes off to the suburbs to stay with his uncle, who bought a house with money he won in a lottery.

Craig again spends the day smoking pot — with his Uncle Elroy and Elroy’s sexually rapacious girlfriend, and with Elroy’s son Day-Day and his friend from work (before they get fired). When they have to raise $3600 to pay off delinquent property taxes, it never occurs to them to earn it or to go to the bank to get a home equity loan. No, clearly the best choice is to steal it from some vicious Latino drug dealers across the street.

Parents should know that the movie is extremely raunchy and includes just about every kind of material except for graphic violence that parents try to keep away from kids. Parents whose kids do see this movie should at least try to talk with them about the portrayal of women (either sexual predators, compliant bimbos or terrifying harridans) and minorities and drugs as a way to bond and to escape worries.

This true story of a boy from a small town who dreams of becoming a rocket scientist is one of the best films ever made about the thrill and hard work of science and a great family movie.

In 1957 the Soviet Union launched Sputnik, the first man-made orbiting satellite. Thanks to Miss Riley (Laura Dern), a gifted teacher, Homer Hickam (Jake Gyllenhaal) and his high school friends peer up into the clear October sky over their tiny West Virginia coal mining town to see its tiny spark drift across the stars. Homer dreams of being a rocket scientist. His father, John (Chris Cooper), the mine supervisor, does not understand Homer’s longing for wider horizons. But others do. Miss Riley roots for “the unlucky ones.” Homer’s mother covers the kitchen wall with a mural of the seascape she longs to see. Homer’s friends are glad to be a part of something new and important, and the community is proud to have a hero.

We know from the beginning where this story is going, just as we know with “Rocky.” The triumph of the underdog is one of literature’s most enduring themes. As long as it is done well, audiences are happy to go along and it is never done better than it is here. The script, the production design, and the acting are all superb. Gyllenhaal’s expressive eyes show his longing for the stars a million light years away and for his father’s approval in his own home. Cooper makes a role that could have been a one-dimensional tyrant multi-layered and complex, even sympathetic. Plot twists that might seem heavy-handed or melodramatic work because we know they really happened, and because these characters make us believe. We care so deeply about them that when we see real home movie footage of the real-life Homer’s experiments over the closing credits we feel as though they are a part of our family.

Parents should use this movie to talk to kids about how Homer, not a great student and not especially strong in math, became so inspired by an idea that he begins to think in new ways. Using math and science to solve problems made it real to him, and the work involved was — like the eight- mile walk to his experimental launch site — unquestionably worth it. They should also talk about why it was hard for John to support Homer’s ambitions, why his mother saw it differently, whether Homer made the right choice in going to work in the mine — and in leaving it, how kids at school treat the “nerds” and why, how people are evaluated differently in school than they are once they get out, and how life in 1999 is different from the world of 1957.

Parents should know that a drunken stepfather beats up one of Homer’s friends in one scene (and is stopped by John) and that there are some very mild sexual references.

Kids who enjoy this movie might also enjoy “The Corn is Green,” another true story about a boy from the coal mines who is transformed by education. Two different versions are available, one with Katharine Hepburn and one with Bette Davis.

Based on Anna Quindlen’s novel, this is the story of a young writer who learns the value of her mother when she goes to care for her during her treatment for cancer. Renee Zellweger plays Ellen Gulden, a New York Magazine writer who has always rejected her mother’s homey values to follow the career of her father, a distinguished literary critic, professor, and author. As Ellen cares for her mother, she finds that her father is less than she thought, and her mother is more. In understanding and accepting her parents as fully human, Ellen begins to be more fully human herself. She gains an appreciation for her mother’s strength. The community and domestic projects Ellen had seen as unimportant busywork she learns to see as an essential source of sustenance. Meryl Streep shines as Ellen’s mother Kate, not afraid to show us the irritating side of Kate’s sunny personality and the impatience she reveals as she acknowledges that she has to insist on her opportunity to talk about what is important to her before it is too late. William Hurt plays Ellen’s father George. He show us that his hypocricy comes from weakness, insecurity, and fear, in a way harder for Ellen to take than if it had been based only on selfishness.

Parental concerns include the brief profanity that earns this film an R rating as well as intense and disturbing scenes concerning Kate’s illness and the issue of euthanasia. The movie probably will not have much appeal for teens, who are seldom ready to consider their parents as fully human, but those who want to see it may come away with a better appreciation for the complexity of relationships and the diversity of accomplishments.

If the real-life Robin Williams were a doctor, he would be the real-life Patch Adams, who believes that doctors should treat the patient, not the disease, and that sick, frightened people need to feel that those who take care of them are paying attention. So it is easy for us to come to this movie prepared for something warm and reassuring. Unfortunately, the movie is so unforgiveably manipulative and shallow that in the concluding climactic scene, set in a courtroom just in case you weren’t sure who the good guys and the bad guys were, you may find yourself rooting for the uptight by-the-rulebook dean of the medical school.

We meet Patch when he is a patient in a mental hospital, where he learns that his mental health is improved more by helping other patients than by treatment from the doctors. From there, it is off to medical school, where he manages to be at the top of his classes while spending most of his time at the hospital making the patients laugh. How could the faculty object to this? Could it be because a first-year medical student might interfere with a patient’s treatment and cause serious harm? No, it can only be because they are fuddy-duddies who just can’t remember how to have fun! And while we’re on the subject of fun, how about stealing supplies from the hospital for a little clinic that Patch and his friends set up in their spare time? And what goes on at that clinic? Medical students who have no idea how serious the problems are “treat” patients with bandages and kindness. When the inability to diagnose the severity of illness has the most profoundly tragic results, Patch only has a brief crisis before putting that darn clown-nose back on and getting back to the serious business of making patients laugh.

There are a lot of important points to be made here about the dignity that all of us deserve when we are scared and vulnerable and about the importance of humor in the direst of circumstances. But this movie undercuts its own arguments by presenting us with a hero who is more narcissistic than humanitarian. The old joke about Hollywood is that the only thing that matters there is sincerity, and once you learn to fake that, you’re all set. This movie, with its adoring bald kids and old lady swimming in noodles and bedpan clown shoes, cannot even manage to fake it.

“The Wild Wild West” has the weak, weak script. It is not unusual to see a trailer that is better than the movie, but in this case the music video is brighter, wittier, and more exciting than the movie.

Will Smith may still own the 4th of July, but this year’s entry is much weaker than his 1996-97 one-two punch of “Independence Day” and “Men in Black.” His unquenchable appeal goes a long way toward making up for poor plotting and dialogue, but not far enough, leaving us with a summer popcorn movie — impossible to resist at the time, but leaving you a bit queasy afterward.

The 1960s television show starred Robert Conrad in a bolero jacket and very tight pants as a Civil War era secret agent. Like the newly popular James Bond, West was a spy who was infinitely attractive with the ladies and who always triumphed over the bad guys, who were always maniacs intent on three things — total world domination, killing West in fiendishly complex contraptions, and making sure that they conveniently explained all their plans to West in time for him to escape from the fiendishly complex contraptions and save the world again. West’s sidekick Artemus Gordon was a master of disguise and technology. Their most frequent foe was Dr. Loveless, played in the series by Michael Dunn. And the whole thing was very much tongue in cheek.

The big-screen version has Will Smith as West, all bolero jacket, tight pants, and attitude, with Kevin Kline as Gordon, Kenneth Branagh as Dr. Loveless, and Salma Hayek as the lovely Rita Escobar, who flirts with all three men and spends much of the movie in fetching 19th century lingerie with a brief detour into a union suit with the trap door open. The plot remains the same — Dr. Loveless, vowing revenge for losing his entire lower half in the Civil War, seeks total world domination, and West and Gordon have a week to stop him. There is some attempt to deal with the fact that West is a black man at a time when most black people had only recently been freed from slavery, but the fact is that the entire movie is so completely preposterous that the effort is awkward and inconsistent with the tone of the rest of the film.

Indeed, the overall tone of the film is awkward, not giving Kline or Hayak much to do, though Kline has a nice turn as President Grant and Hayak looks fetching in her undies. Branagh is happily over the top as the bad guy, there are some cool special effects, and Smith’s charm and grace carry it a long way, but not far enough to make it anything more than a pleasant diversion less raunchy than “Austin Powers.” Parents should know that there are some PG-13 sexual references, including prostitutes and Loveless’ impotence and a lot of cartoon-style action- violence.
