Like you, I'm a huge super hero fan, but never really got the appeal of Thor. I always thought of the entire Thor series as a pompous losery kind of thing. His weapon of choice is a hammer? Mmmm, okay....
But this movie didn't disappoint. Was it predictable? Sure. Was it chalk-full of the dreaded Natalie Portman, yes, but the movie was not half bad. I'd go as far as to say I like it better than Spider-man 3, better than Batman & Robin, better than both Hulks, better than Superman 4 and Superman Returns put together, better than lots of stuff.
What makes Thor fun is its sense of humor about itself, and Chris Hemsworth, (also seen as George Kirk in 2009's Star Trek,) is perfectly cast. I'm so sick of bland actors playing action heroes just because the casting director thinks action movies only need strongish looking men to pull the part off. (Don't look at me like that, Sam Worthington.)
So, here's the deal, Thor and Loki are gods, they have a dad, (Anthony Hopkins, above,) who is going to name Thor king, but changes his mind because Thor is a little hammer-happy. Thor is banished to Earth (Oh the despair! Anywhere but Earth!) and the king tells Loki that he's not really his son, but of an alien enemy race - the Frost Giants. (But just between you and me, I think he's really from She-Ra. Remember Lo-Kee? Found you this time, you little menace!) So, Thor's on Earth, he can't use his hammer, and apparently he falls for Natalie Portman. Except, the only way we know he's in love is because he says so. Can we get some relation development in here? This movie needs to go to couple's therapy and learn how to have a couple. (That is the point of it, right?)
