I guess I had the opposite reaction to the trailers than others here. I've been pretty excited for this movie ever since seeing the original footage from comic-con despite not being an avid Thor aficionado. Finally saw it today and luckily it didn't disappoint. Loved it from start to finish. Really didn't want it to end. Like others have said it was just a fun movie with a great blend of fantasy with reality.
Asgard was an amazing environment, wish we got to see more of it. Jotunheim was equally impressive with its chilly and spooky desolateness. Loved the look of Laufey and the frost giants. Although not as large as they were in the comics they still ended up being larger than they appeared to be in the trailers. I appreciated the display of Thor's sheer power as a God, something I hoped they would be able to convey effectively. Loki was probably the best villain out of the Marvel U movies so far.
The acting was solid throughout. Portman and Hemsworth had good chemistry and even though their relationship seemed somewhat abbreviated it still worked pretty well. The humor was natural and not too forced or out of place and Kat Dennings didn't end being as annoying as I thought she might be.
All in all a really enjoyable comic book flick. For right now I'd say it beats out Iron Man as my current favorite so far. Can't wait for Captain America!
Also I really liked the post credits scene, probably my favorite of the easter egg scenes so far since it sets up both Captain America and Avengers nicely.
So what were all the easter eggs in this movie? We had Stan Lee (obviously), the Casket of Ancient Winters, the nod to "Donald Blake" as Thor's alias, the mention of Banner's disappearance, Hawkeye, the artifact/character in the post credits scene, the Infinity Gauntlet, Warlock's Eye and
other items in Odin's Vault, Stark reference when the Destroyer arrives. There was also a reference to Hydra in the script but I think it was cut from the film.
