I've just seen Iron Man 3 and my answer to this question is Captain America.
Tbh, I really don't see why people think Iron Man 3 is that good, it took 25 minutes to start and then the only really good scenes were in the final 15. In between all I saw was filler, bad jokes, an annoying kid, cardboard villains, an obvious swerve with Kingsley and a bombastic soundtrack that, like The Dark Knight Rises, failed to trick me into thinking I was watching something great.
More than anything else, this movie has finally made me realize that my tastes have changed and comic book stuff no longer seems to appeal to them. It's unfortunate, but I guess that's part of life.
