Iron Man is a great super-hero flick, but be warned, it is not appropriate for young kids. Realistic war violence, a torture scene, and the (off-screen but clear) murder of hostages all add up to a film that will disturb some viewers under 12. Take the PG-13 seriously. That said, it is one of the classic super-hero movies, right up there with the best of the Spider-Man, Batman, and Superman franchises. Robert Downey Jr. is perfect as the playboy Tony Stark, and the super fights and action are all well done.
