I hereby dub it "Much better than I expected."
Really, the thing I liked most was I got to see everything I wanted to see in Thor's first fight scene. He twirled the hammer, he threw the hammer and it came back, he flew with the hammer. I could have left right after that battle was over and I'd still have been satisfied.
Of course, the downer is I'm sick of seeing Natalie Portman's face freaking everywhere. Really. She played Luke and Leia's mother and a crazy ballerina lady. I get it. We're supposed to love her. Can we find another actress now?
And Special Agent Coulson rulzzzz!
That is all.
