Thought the movie was good, not as good as Iron Man, but good nonetheless. I had no problem with the "lack" of action considering Tony Start had a lot of personal demons in the source material. I think if they had just slapped him in the suit and had him do some fighting it would have been a huge disappointment. If I wanted crap, schlock action I would watch Transformers. Since I have some scruples and don't want to see Iron Man ruined the way the Val Kilmer/George Clooney Batman and Sam Raimi SpiderMan movies ruined their characters by making them parodies of themselves, I enjoyed some character development.
The Dark Knight is probably the best comic/super hero movie ever but the Iron Man series so far is the best series. Batman Begins wasn't great, Superman Returns is just bad, the Edward Norton Hulk was good but he won't be coming back, Spider Man 2 and 3 were laughable at best, X-Men kept getting worse...
Probably the only one that may be as good or better than Iron Man as a series so far is Hellboy.
