I'm a huge comic book movie fan, and Thor did not disappoint me! I do think that it suffered a little bit by trying to tie itself to the Avengers movie coming out next year. Hopefully Captain America doesn't suffer the same problem. That's just a minor issue thought.
Hemsworth owns the role of Thor and Hiddleston was pretty close to perfect as Loki. Don't know how much of an audience it will draw outside of fans of the genre, but who cares! I'm happy!
