Just saw Iron Man last night - never knew anything about it, or the comic books, but I really liked the movie. Robert Downey Jr is fantastic - I think casting great actors (a la Christian Bale as Batman) is the new trend now, which allows the "action" movie to still have some depth and heart, which this does. It was funny, it had great action and tricks, and the main character was really well-developed, so you got where he was coming from. A definite see!
