I've been a big Thor fan since I was a kid. Thor was the number one comic book I followed and still will pick one up today if I stop by a comic book store. I was very anxious to see this movie and how it would play out. I have to say I was very pleased. IMO they followed the comic book story line fairly close. Chris Hemsworth was terrific as Thor, and the other actors played the gods just as good. Natalie Portman and the other "Earthlings" did a great job too, with maybe just a smudge too much, let's say staring time, between Thor & Jane.
There was just enough humor added to give you a laugh here & there, but over all they played it serious (not like the way Seth Rogen turn the Green Hornet into just another Seth Rogen movie with action thrown in. Sorry, still very upset over that). The action scenes in Thor were great. What I like the most is the way Thor did things when fighting that he would do in the comic books. Also, the Destroyer, I felt was very well done. (For anyone who seen the remake of The Day the Earth Stood Still, and was upset by how Gort was, rest assured, the Destroyer is what Gort should have been.)
As far as the "alien" theme, I was very worried about that until I seen the movie. Again, IMO, I think they handled it very well...and even offer a explanation by Thor himself. Also, I was a bit nervous that Marvel decided to not have Thor become Dr. Blake, but after seeing the movie, I really think this was the right decision. I think it would have been a lot harder to make a good movie with Thor changing back and forth. Since Thor is really a god, it's not like Iron Man, or Spiderman, who are humans with added powers and just put on a costume. Also, though I hope the box office takes will seduce Marvel into making a sequel to Thor, it's very obvious that Thor is being used as a setup for The Avengers. I have a feeling Marvel is betting the farm on that movie.
One last note, I seen Thor in 2D. All reviews I read said 3D added nothing to the movie and at times took away from it. Since I haven't seen it in 3D I can't comment on that, but I will say it looked fantastic in 2D, and the Rainbow Bridge was pretty cool. Don't forget, Thor was post-production 3D.
