I've posted this in another thread concerning Ang Lee's "Hulk" but I think it is a useful contribution to this thread as well. Besides self-plagiarism is the sincerest form of intellectual narcissism).
Frankly, until I saw the movie I never actually "got" the character. I could never understand the Hulk being a "superhero". It was only after seeing the film that I understood that the Hulk really is a classic tragedy.
Banner's hubris has brought him great power but with a great price. He is being punished for thinking that he could duplicate a god's power. And like every great tragedy there is a sense of inevitable doom around the story. The Hulk cannot have a happy ending, and everyone involved in the story senses that. The best Banner can hope for is redemption for his past deeds, and in the context of the movie, the sins of his father.
After seeing the film, I started to look at the character from a different viewpoint and now he's become one of my favourites. Stan Lee said that with The Hulk he was trying to do a modern version of Frankenstein and I think he has succeeded.
The Hulk is searching for his identity and place in the world and finding only rejection, fear and hatred. In response to this he transfers his fear and hatred to Banner, his "creator". Banner, on the other hand, fears losing control to his own implulses and emotions, which really are the genesis of the Hulk and also feels he must be punished for them. He also fears the fact, and the movie brought this out very well, that he enjoys the loss of control that triggers his transformation. In Frankenstein, the monster felt that the only way he could enter society was to replace his own creator. This is the classic situation that the Hulk is in. Both the Hulk and Banner are in competition with each other, which means they are in competition with themselves. And in this competition there can only be one victor and even that victor is not the winner.
Comic books are not a genre they are a medium. Tha means you can use them to tell any type of story you want. Ang Lee understood that. He wanted to tell a story of alienation and of a man railing against his preordained fate. Look at Hulk in a cursory manner and you see what are the traditional trappings of a superhero comic. A secret identity concealing a powerful doppeganger capable of seemingly dealing with problems the original can't. But if you look deeper you see that those trappings are merely trappings. There is no secret identity in Hulk. There are two competing and antagonistic identities. Unlike other "superheroes" Banner is not, for most of the movie, trying to balance the two sides of his life, he is trying to suppress one. And the Hulk is trying to emerge and suppress Banner.
The story cannot have a happy ending. It shouldn't have a happy ending, that would be cheating. If Banner suppresses the Hulk, or vice versa, it is a tragic loss of a character, essentially a death of one of our protaganists. What we end with in the movie is a compromise between Banner and Hulk. And in the parameters of the story, a compromise is a triumph.
