Re: TIH vs. Ang Lee's Hulk
I agree TIH is still canon to the "FILM" Universe.
But regular audience will NOT get lost in the Avengers 2012 if they did NOT see TIH.
The films of Ironman, Thor, and Captain America has so much of an impact that everyone has to watch them before they watch the Avengers film to truly experience the whole scope.
TIH, however does not. The movie is NOT BAD but it does not compare to the other 3.
Those 3 were ORIGIN STORIES. TIH is NOT. Unless you count the opening credits.
Hulk's Origin can simply be explain in one line in the Avengers film as a brilliant scientist who is an expert in Gamma Radiation who became the powerful Hulk.
I'm NOT SAYING IT'S NOT CANON.
I'm saying that general audience will not miss anything in Aveners if TIH was never made.
TIH is an AVERAGE Superhero Movie at best
