Hitting Thor with a vehicle...twice, Thor's epic lines, Loki's costume, the gatekeeper.
Tedious backstory and all the Odin references. Examples: Odin-sleep.
Natalie Portman is a hungry scientist type person looking for
Thor had a good start - all minute of it. The weather chasing scene was tense enough to create interest, and mysterious enough (because they hit a "mysterious" guy with their giant weather van) that it tided the viewer over the awkward/dull/tedious backstory. Mostly I didn't like it because Thor started off as such an unlikeable character. He was so high school. Returning to the story on Earth was a relief, but it was nice to return to Asgard (insert Stargate joke here) and it's rainbow bridge for the development of the plot arch. Maybe it's because costumes really make super hero movies. Best of all was Thor striding around Nowhere'sville like he owned the place. His one liners were epic, and turned the movie from a serious super hero flick into a super hero flick/comedy. I give Thor a 4 out of 5, because as super hero movies go, it was pretty good.
