I never was interested in the Hulk to be honest.. didn't read his comics so I won't know.
I think when acting in a superhero comic adaptation, they should act like the how the hero was in the comics. Good examples are Robert Downy Jr. and Hugh Jackman.
Bad examples include Tobey Maguire for making Spiderman look emo and too damn depressed. If I recall, Spiderman is a funny sarcastic genius.
And even though I love this actor, Nicolas Cage's Johnny Blaze isn't right either. Johnny Blaze is a hardcore smoking drinking badass. Cage just didn't put any effort on it.. I know he wanted his own version of him, but he didn't put much effort into it..
