Go to see it yesterday in 2-D. It was OK. Decent, but not great. Not as good as either Thor or X-Men First Class.
The pacing of the story was a bit off for me and I just get sick of this tired formula of the hero having to have a love interest. I doubt that an intergalactic cop needs a girl friend to remind him that he needs to save the earth (or any other planet).
Complication makes it easy to explain failure.
