I was busy all weekend, so I only got to see the movie tonight (in 2D; hooray!). I'd give it an A-. Not in the same league as Iron Man, but better than The Incredible Hulk and Iron Man 2. The movie did a much better job of incorporating foreshadowing for The Avengers than Iron Man 2 did; SHIELD's presence around the hammer works fine, and the after-credits scene is actually substantial. Hemsworth was great as the lead, and the other actors were generally strong, if often with not a lot to actually do. If I had to guess, I'd say that the sequel will probably do more with Sif, in particular. The rendering of Thor's powers was great; the next Superman movie should aspire to that sort of stuff.
