I avoided it because
1) Eric Bana is totally wrong for the role. Miscasting Banner is a deal-breaker for me. Banner needs to have an almost savage intelligence that is the counterpart to the Hulk's savage strength. Very few actors could be said to have a savage intelligence, but Edward Norton is one of them.
2) The stuff about Banner's father sounds like idiotic psychobabble to me. A comic book movie should get to the point, be clean, lean & mean and not belabor or overcomplicate things.
