Iron Man 2 is mildly entertaining, but the problems are glaring. First, the "hero" of the story is actually quite obnoxious - what he learned from Iron Man 1 didn't seem to transfer over. Second, too much talk, talk, talk without any content. The dialog didn't really move the story along. It was mostly made up of Tony Stark arguing back and forth with every character in the story. Third - the under use of a really good bad guy. Mickey Rorke makes a great bad guy, but they didn't use him near enough. Fourth - The over use of the obnoxious bad guy - Hammer just got on your nerves. Fifth - the under use of a great actor like Samuel L. Jackson - who was he suppose to be in the movie and why was he even there??? All in all it was a bit of a mess - it could have been so much better.
