Best superhero movie I have seen (going back to the original Superman movie in the early 80s). I was a bit doubtful about Downey as Tony Stark, but he TOTALLY pulled it off. This movie will not disappoint on any level - awesome introduction to Iron Man, great action scenes, just the right amount of comedy, and the requisite romantic tension between Tony Stark and Pepper Potts. Make sure you stay past the credits - there is much more to come!!!!
