I saw Thor finally on Tuesday night. My overall reaction is that it was a good to very good movie. There were a few spots where it didn't work for me, but overall I was very happy with the results. Like most Superheroes, you can never find someone who looks 100% like the character and be a good actor. Chris Hemsworth was great a Thor, I believed instantly that he was the jovial, juvenile God of Thunder. He played him on the edge of being a parody, but was able to rein it in. I believe that has a lot to do with Kenneth Branagh direction. Tom Hiddleston was very good as Loki, not your standard bad guy. I liked that he didn't play him as the sniveling coward but more of just the weaker brother. I will only say that Anthony Hopkins was Anthony Hopkins, take that as you will. I thought Natalie Portman's Jane and Thor had real chemistry, it was nice to see "movie" instant romance develop and be palpable. The lone low point is Kat Dennings Darcy. I really didn't think her character added anything to the movie and felt shoehorned in to add additional comedy, which I don't think the movie needed.
My main complaint is the convoluted story. While many are quick to blame the writers, who maybe at fault. I'm not sure if this movie was hurt more in the editing bay then the word processor. I have a sneaking suspicion that a "directors cut" on blu ray will smooth some of the narrative problems out. Things seamed awfully rushed, logic jumps are made all in the name of moving the movie along. While I don't think the movie was epic, which I think it could have been. To me they though small, and made a more intimate movie.
I can't wait for this to hit Blu Ray, hopefully with a directors cut.
