Saw it in 3d. The movie was pretty entertaining, but I wish they showed more storyline of Thor's time on earth. It was mostly about stuff that happened in Asgaard, which is the god-realm where he's from. That part made the movie seem more like one of those old greek/roman/viking god movies rather than a superhero comic movie.
Also, I still really don't like how all movies these days seem to be coming out in 3D. To me, it adds a bit of cheesiness to the movie... like, they would add scenes in the movie that are made to showcase the 3D technology, like Thor would throw a hammer towards the screen making it look like the hammer is coming towards you.
