"Ironman," totally. My wife even wanted to see it again and she doesn't usually go for that type of film. That movie will be added to our DVD library when it comes out. Surprisingly, my son didn't like it - the Ironman mask creeped him out. I've been holding off on seeing "The Hulk" for just that reason.
Upon further reflection, I put "WALL-E" at the bottom of Pixar films. It's not awful, just a little short on story.
