I have to say this movie surprised me in a few outstanding ways.
1. The story like the script moves fast and presumes you know the Hulk back story as most do or should. That was a good thing 'cause I think that's where the 1st Hulk movie slowed down too much.
2. This movie shows that with all the power Banner has as the Hulk he truly has nothing as after each transformation he's left lost, alone and for all intents and purposes a homeless man begging for his next meal.
3. The action and the fight scenes got more intense each time until the end just blew me away. I realized that for the first time in all these Marvel [or DC] movies I was truly, truly watching a full spread comic book unfold before me!!!
Downside? Yeah the chemistry between Norton and Tyler like their dialogue is a little flat -- actually Tyler is better with the Hulk then Norton lol but you really don't mind as its a necessary part of an otherwise good story and great comic book movie!!!
