This movie was MUCH better than what I was expecting or hoping for. I would pay to go see it again.
For non comic book fans I would give it 3 out 4 stars, for all you Marvel Zombies this is a 4 star movie so get in line now.
This movie is really more based on "Ultimate Thor" instead of the main marvel world Thor, but that should be no surprise since most of the Marvel movies have been closer to their Ultimate line of comics.
The 3D effects were actually quite good, none of the "in your face" 3D effects which to me ruins the experience, just makes the movie look much more life like.
If you have read any of the pre-release press on the movie you know that they have changed Asgardians from "gods" to "aliens". This was done to make sure that it played in middle America. I was extremely worried about this when I first heard about it. It was not that bad, you can actually walk away thinking they were "god like" beings or if your religious views don't allow that they are "aliens with fantastic powers". For you DC fans, think of them along the lines of the "New Gods".
So the number of people involved with this movie which have won major Awards in the past is staggering at least 3 actors, the director and one of the writers. Mentioning writers, the story (but not the script) is credited to J. Michael Straczynski.
Stan "the Man" Lee has a brief, but funny Cameo. Look for it around the "Crater".
Lots of minor references to : SHIELD, Stark, Gamma Ray Scientists , etc
One other Marvel hero is in it, but he is not referenced by his hero name. Does the name "Clint Barton" mean anything to you?
They were able to slip in a reference to "Donald Blake" which made me happy.
Make sure you stay all the way through the credits. About a 2 minute clip which is being used to setup the Avengers movie (and MAYBE the Captain America movie), it has every ones favorite S.H.I.E.L.D director. A major Marvel "artifact" is shown in this clip.
Also when in the Adgardian War room, look very carefully at the glimpses of the artifacts, many famous Marvel artifacts are shown. From interviews I know the infinite gauntlet is there, but I missed it.
