I have only one criticism of this movie. As with a lot of the "comic book to big screen" conversions, this film doesn't quite know how to integrate the two very different mediums. As a result, we get moments and characters that I wanted to be tweaked a bit further over the top. More comic book, less movie.
Robert Downey Jr. is the perfect mix of swagger, genius, and yes, emotion. He represents what's great about the new rash of comic book heroes going all Hollywood on us: they bring an emotional depth to the characters that makes us care about them.
I hope there's a sequel. But I hope it takes the characters and the story further. If so, I'll go along. Just get me one of those flying suits.
