In the Thor movie, what I'm looking forward to the most is the epic battle between Thor and the Destroyer, Thor fighting Loki doesn't get me excited as much.
In the Avengers movie, however it plays out, Thor should end up defeating the Hulk because no matter what the gamma rays did to Bruce Banner, he is still only a regular human being, a man. So he can only get so mad, which means he can only get so strong, and no human being no matter how mad or strong he gets, can defeat a God!
BTW, this was my major complaint with the Hulk vs. Thor animated movie, there's absolutely no way Hulk could beat Thor so easily! The female warrior in the Planet Hulk animated movie gave Hulk a better fight than Thor did?
I couldn't believe Marvel portrayed their own character Thor so wrong!
