I have to The Incredible Hulk to watch again (saw it in the theater), but I enjoyed Iron Man more after just a first viewing. The love story in The Incredible Hulk kind of turned me off. I was tired of seeing two scientists get overwhelmed with emotion whenever they were near each other. I like my scientists to be dispassionate robots. The endings of both movies left a bit to be desired, I thought, but still, as far as superhero movies go (okay, one is a rich guy in a suit, and the other is a monster who does heroic things), both were fun.
