"Banner saved Thor's life when he didn't have to"
---But that's true of any superhero comicbook hero ever created (even Spawn). They save people. They don't have to, but they do it anyway, exposing themselves to threats in doing so. In the DVD, Thor went out of his way to save Asgard, willing to give up his own life, Thor didn't learn anything new from Banner. Banner, was in fact unwilling to merge with the Hulk at first. It was only when he needed to save Thor which prompted him to do the right thing. Difference, Thor was willing throughout the movie. Banner, only during that one pivotal moment.
True, but something else was their intent. Hulk vs just really bugs me because it was an animated fight people had long look forward too only for Thor and all of Asgard to get thrown under the bus. Seeing Wolverine hold his own and in the commentaries Yost and Kyle saying they left Wolverine vs Hulk a draw for the fans only to be crackling jokes throughout Hulk vs Thor like how ____ will beat Hulk to me just really rubbed it in.
