I also just watched Thor for the first time. I liked it although I don't think it's awesome. It certainly feels like a comic book come to life, but in a good way. And, yes, it does give you some decent backstory to the character.
I did like Thor's character arc from selfish puts to worthy hero.

there's this giant vortex of doom we can see, which defeats their "discovery" since people should see that damn thing whenever Odin has The Warriors Three go for a pizza run. This seriously pisses me off, as every problem I had up to this point was more a matter of taste rather than substance. This was a matter of Michael Bay's nephew ghost writing.
