I loved the Thor movie. My only real complaint with the film is that it was an origin story movie and thus subject to the mandatory de-powering arc of the plot. The best parts of the film were those when Thor was actually still endowed with his abilities IMO; although the action scene where he attempted to retake his hammer was very well done.
This is one of those movies where I am really looking forward to a sequel. Alas the next appearance of Thor will be in the Avengers movie, rather than another tale of Thor himself out in the greater multiverse.
I loved the special effect sequences, as well as the whole look and feel of Asgard. Wonderful work there. I would dearly love to see more movies like this that have supernatural or mythical characters, that are set in realms other than Earth.
