I just arrived home from a late night show of Thor. I had some doubts on whether I would like the movie. But it turned out to be pretty nice. Of course, Marvel is yet to find anyone who can match the charisma of Robert Downey Jr (Iron Man) but the entire series is shaping up well. They have of course messed up with the character of Hulk which is going to be played by Mark Ruffalo.
I watched the 3D version. I take the risk every time. This one was not a mistake. 3D worked well in Thor. Really enjoyed it. Check this one out if you are following the entire series that leads to The Avengers movie. Captain America is next I believe.
