All of this sounds like everyone is coming around to my only complaint about the film that I have been talking about in other threads.
1. Why does Banner expose himself to radiation? He knew what he was doing right?
2. Why is Hulk a different, more primal personality than Bruce, but Blonsky retains his intelligence and personality?
3. Why does simply being exposed to radiation turn Bruce into a monster? (I know the initial idea in the comic was just that simple, but over the years they added more ideas to make this plausible. Even the TV show at least made the statement that Banner had an anomally in his DNA that reacted with the Gamma).
Those are the questions this movie doesn't answer.
My complaint I have been harping on is if they would have simply allowed this to be a possible sequel to the '03 film, all of these questions wouldn't exist. Those answers would have carried over from the last film instead of the very under-developed origin flashes. But, oh well.
Maybe an extended cut DVD, or even a sequel (you hear me God?!) will answer these questions. We'll have to wait on both.
