Only a kid could love it, but they do.
Parents need to know that the movie has violence, including one grisly death by disintegration. Characters use some strong schoolyard language ("screwed up," "play doctor," "Are you in special ed?") and there is a locker room scene in which a woman snatches the towel from a boy's middle and snaps it at another boy's crotch. (The flesh-colored underpants the boy was wearing under the towel are reassuringly evident.) The adult woman spy dresses like a comic book character, but she is strong and capable. The head of the CIA is a black man. There is a joke about using the special x-ray glasses to peek at women's underwear and an adult makes a joke about breasts. It is highly insensitive to have characters use "special ed" as an insult. Most troubling is that one of the young people in the movie is directly responsible for the death of a bad guy -- usually, in movies for this age group, they are careful to have the bad guy killed as the result of his own actions, like falling off a building when he lunges for someone. Some audience members may be upset about this.
