Re: TIH vs. Ang Lee's Hulk
The best part of TIH was the first act. The whole premise of Bruce hiding in Brazil, trying in vein to find a cure; brilliant. And a pitch perfect mixture of the comics and the classic TV series.
That said, after he exits Brazil, the film needed to have much more substance than simply his reunion with Betty, and Ross' obsession with the Hulk. That's where they should have really delved into the Hulk and Bruce as characters.
It's like a non-consecutive 24-hour dance party.
