The technological mastery and all-star cast all but obscure the one real problem of this movie — it does not know who its audience is. The computer animation — and the ad campaign — suggest that it is directed toward the audience of its predecessor in this genre, the classic “Toy Story.” That movie focused on themes that touched both children and adults. “Antz,” instead, seems to have spent most of its energy on its astonishing visual effects and outstanding voice performances by some of Hollywood’s top stars, with its theme of individual spirit in a world of conformity an afterthought, and a muddled one at that. The witty script aims its humor at adults who can appreciate the in-jokes. The characters have little kid appeal, and the violence, including the deaths of two characters and the slaughter of thousands of animated “extras,” is much too intense for younger children.

Woody Allen provides the voice of Z, the movie’s hero, and we first see him on the analyst’s couch, complaining about his feelings of inadequacy. A worker ant among millions of others, he longs for some individuality. When he meets the ant princess Bala (voice of Sharon Stone), he longs to see her again. So he persuades his friend Weaver (voice of Sylvester Stallone), a soldier ant, to switch places with him. Weaver enjoys being a worker, but Z finds to his horror that he is being sent into battle by the meglomaniacal General Mandible (voice of Gene Hackman). He is befriended by Barbados (voice of Danny Glover), who is killed, along with all of the other soldiers. Only Z escapes, and it is up to him to rescue the rest of the ant colony from Mandible.

The visual effects are dazzling, and the movie also provides a welcome reminder that performers as inextricably linked to their apearance as Allen, Stallone, and Stone are capable of superb vocal characterization. Parents will want to talk to their children about when to question authority, how to balance individuality with community norms, and how what seems like garbage to us may be “Insectopia” from another perspective.

Adele (Susan Sarandon), a free-spirited teacher, takes her 14 year old daughter Ann (Natalie Portman) to Los Angeles in a gold-colored Mercedes. Ann resents her mother for taking her away from everything she knows, and she misses her family and friends in Wisconsin.

Adele dreams of a more glamorous life and wider opportunities for Ann. They struggle with each other and take care of each other until Ann leaves for college. Once Ann is ready to be on her own, she can admit to herself and to Adele how much she loves her.

Adolescence begins with it an avalanche of mortifying self-awareness. All of a sudden, everything is embarrassing, especially parents, in whose eyes teens can see their past more easily than their future.

This movie does a good job of portraying that stage of life from both the teen’s and the parent’s perspectives. In the first scene, Ann is embarrassed that Adele is eating so loudly, even though they are driving through the desert with no cars anywhere in sight.

Adele’s relish for more than she can find in Wisconsin is unsettling to Anne. Adele says, “I wish someone had kidnapped me back when I was your age,” and Ann responds, “So do I!” Part of Ann wants Adele to be the magical parent who can provide everything without effort. But when she begins to accept Adele’s mistakes and vulnerability, she can begin to grow up.

Adele seems to have endless optimism, leaving for Los Angeles on the strength of “an interview and a great outfit.” She blusters her way into a mansion by pretending to be a possible buyer. She forgets to pay the electric bill but is always ready to get some ice cream. Heartbreakingly, she thinks that a one-night stand with a dentist means that her true love has arrived.

As teens and parents struggle with independence through those years, it never seems that they are both ready to let go at the same time. Ann says that what keeps her going is knowing that someday she will leave Adele. A kindly policeman tells her that “you leave her when you are ready not to come back,” and that gives Ann an ideal of herself as an independent person to reach. Then, when she and Adele return to Wisconsin for a funeral, she sees how much closer to that ideal she has become than she would have if she had stayed.

Throughout the movie, Ann and Adele do a sort of relationship minuet, stepping toward each other, and then away. Ann imitates Adele in an acting audition, and Adele sees that she appears self-deluding and foolish to her daughter. Adele often acts more like Ann’s sister or even daughter than her mother. But when she needs to be the adult, to make the sacrifices necessary to help her child, she comes through.

Parents should talk about Ann’s decision to have sex with a boy who has a crush on her, which is more a reaction to a cool reception from the father who abandoned her than a reflection of a mature and intimate relationship. When she invites him over and tells him to take off his clothes, her words are tough, even cold, but when he walks over to her she throws her arms around him and holds him as though she is desperate for human contact.

Families who enjoy this movie will also enjoy “Tumbleweeds.”

This is a very scary movie about a very scary subject — terrorism. Indeed, its release was delayed due to concerns about the sensitivity of the material. Jeff Bridges plays Michael Faraday, a professor who specializes in terrorism, still grieving for the loss of his wife, an FBI agent who was killed in a Ruby Ridge-style shootout. He is befriended by a new neighbor, Oliver Lang (Tim Robbins). At first, Lang’s family seems like an all-American family straight out of an “Up With People” concert, but Faraday begins to suspect that under their bright smiles and peppy friendship might be something very sinister.

Faraday’s friends think that he has become a little unhinged from his wife’s experience. But as he continues to investigate, he discovers more and more disturbing information about the Langs.

This movie will give thoughtful teens some things to think about — balancing the need for security against individual rights, the difficulty of deciding whom to trust, and the factors that lead to hate crimes. The references to acts of terrorism in the US that are so close to reality you will think you recognize them make this more thoughtful than the usual thriller. The very first image, of a boy walking in an immaculate suburb, bleeding from an accident, sets the stage for the unsettling story, and the ending is not only scary, but hauntingly so.

The summer thrill ride movie is becoming as much of a 4th of July tradition as the picnic and the fireworks, and the 1998 version is “Armageddon,” the second movie of the year about a meteor headed toward earth. While the plot line is predictable (think “Dirty Dozen” crossed with “The Right Stuff”) and concocted almost by recipe (take one tough but lovable hero — Bruce Willis in his “Die Hard” mode — and add in a lovably diverse group of misfits, then wisecracks to taste and just a touch of sentiment and a dash of young love for seasoning), the 10-14 year olds in your household (and the 10-14 year old in many of us) will find that it delivers as a summer explosion movie. Parents should know that there are a few sexual references (one major conflict is that the main character’s daughter is sleeping with one of his men) and some strong language, but it is the intensity of the action that is the real cause of the PG-13 rating. Parents should also note that several major characters die. The age recommendation is only for kids who enjoy that kind of roller-coaster style excitement. Families should also discuss some of the moral questions that arise as people have to take risks and make sacrifices for the greater good.

This movie is only slightly behind “Phantom Menace” in anticipation and excitement among kids, but parents need to know that it is very, very, very raunchy, with incessant and prolonged sexual humor. Because it is a comedy, the rating system gives it a PG-13, but the material would clearly get an R if it appeared in a drama. Do not kid yourself that some of these jokes are “over their heads.” Those kids who do not see it — or who do see it and miss some of the jokes — will hear detailed explanations from those who do of references like Powers asking one woman “Which is it, spits or swallows?” and pretty much every woman “Do I make you horny?” In addition, the movie features character names Felicity Shagwell and Ivana Humpalot, a rocket shaped like a penis (described by a series of characters with every imaginable euphemism), references to a one-night stand “getting weird,” an extended sequence in which it appears that a number of objects are removed from Powers’ rectum, and Powers’ inability to perform in bed due to his missing “mojo.” There is also a good deal of potty humor, including Powers mistaking a stool sample for coffee.

The movie is very funny at times and always genial enough to inspire generosity toward the jokes that don’t work. Spy boss Basil Exposition (Michael York) wisely advises both Powers and the audience not to think too much about the plot. So we are left with a series of skits as Austin Powers (Mike Meyers) loses his wife (Elizabeth Hurley from the first movie, who turns out to be a killer robot), meets up with CIA agent Felicity Shagwell (deliciously pretty Heather Graham) and goes after Dr. Evil (also Mike Myers), still plotting world domination, with the assistance of Number Two (played by Robert Wagner in the scenes set in the present and Rob Lowe doing a great Robert Wagner impersonation in the scenes set in the past). Dr. Evil goes back in time to 1969 to steal Powers’ “mojo” with the help of a huge Scot called Fat Bastard (also Mike Meyers) and Powers goes back to 1969 to retrieve it. Meanwhile, Dr. Evil is still struggling with his dysfunctional relationship with his son (Seth Green), who goes on the Jerry Springer show to talk about it with other children of fathers plotting world domination. Dr. Evil becomes very attached to a tiny clone of himself, christened “Mini-Me” and takes time out from extorting billions of dollars from the President (Tim Robbins) to sing “Just the Two of Us” with him. And somehow everyone ends up on the moon.

This is silly fun for its core audience of college kids. They will find the jokes about the 1980’s wildly funny, though they may miss some of the jokes about the 1960’s. Parents should be very cautious about allowing children or young teens to see the movie, and should be prepared to talk with kids who see or hear about it, to answer questions, explain family standards on the use of the language in the movie, and to provide reassurance.
