Is it bad that I can tell more or less the entire story from this trailer? Banner on the run, hating the Hulk inside him, society hating Hulk even more, Blonsky becomes the Abomination, people see how much worse Hulk could be, then Hulk saves them, and enjoys some popularity, and Banner accepts that the Hulk can be a force for good, and runs off at the end to continue to try to control it. They even got the license for the piano music from the T.V. show.
This isn't a criticism, though. The plotting of a Hulk story isn't where the depth comes from; it's the psychology and build-up, while the story mostly ends with Hulk hitting things and Banner running away. Also, they're obviously pulling some cool moments from all over Hulk continuity, like the Banner-into-Hulk air drop from The Ultimates. So I'm looking forward to it (it comes out the day before my birthday, and I always loved the Hulk), but I don't expect to be surprised.
