Parents need to know that this non-animated adaptation of the beloved cult graphic novel isn't just another superhero story and is absolutely not for kids. Even the director has said that he purposely made the movie intensely gory to make a point about the consequences of violent behavior. Sex is paired with graphic violence in a near-rape scene, and characters act in ways that seem highly amoral. They also swear constantly (including "f--k" and "s--t"), smoke, and drink. There's plenty of nudity, with some very graphic sex scenes and a computer-enhanced character who walks around nude (sure, he's blue, but he still has a normal male anatomy). Both the novel and the movie examine complex issues of morality, humankind's basic nature, and the specter of nuclear holocaust. Not light stuff, and certainly not for anyone who expects a simple good vs. evil story. If your teens can tackle heavy philosophical questions, they might be mature enough to make sense of the film's complicated plot. Finally, the movie clocks in at 2 hours 41 minutes most of which are chock full of in-your-face violence, darkness, and peril.
