I saw Iron Man tonight. It was pretty good. Surprisingly, the "super hero" parts of it were the weakest points I thought. For example, the last battle just didn't do a whole lot for me. The other parts were good though.
I thought Robert Downey Jr. played a really good role and came off quite believably as the arrogant, brilliant, playboy type. There's probably a sequel in the works and there's definitely an Avengers movie in the works. They're probably waiting for the latest Hulk movie to fade away, and then the Captain America movie after that. Once those come out, they can all team up and have an Avengers movie.
