I'm pretty sure this is going to be the best film of the summer. While I didn't manage to catch Iron Man, I did see The Incredible Hulk last weekend and walked away unimpressed. Great special effects with zero story and zero real drama just don't cut it. I've heard nothing but good things about Iron Man though.
I haven't seen Batman Begins since it was in the theater, so I'll be gearing up for the sequel by purchasing the Blu-ray release. Can't wait.
