We went to see the Hulk movie last night. I guess it was okay. If I were grading these movies, I'd give Iron Man an A and this Hulk movie a C+. What I didn't like about it was that they just made a Hulk movie four years ago, which I guess we're supposed to forget and I didn't really see that this one was really that much different or better. My verdict is, it's worth seeing, but there will probably be moments when you're checking your watch.
What I did like about it is that the stories of these comic book movies are interconnected and appear to be setting the stage for an Avengers movie that features many of the heroes in one movie. What has always been cool about Marvel comics is that the characters appear in one another's stories. It's one universe and they interact. With the right director, some of those classic stories would make great movies!
