I just saw Thor today. In crappy 3D (I actually removed my 3d glasses halfway through and noticed no difference).

Awesome movie, though. It's not as good as Iron Man, but it works. I especially loved how they didn't try to cheese it with the romance angle, and focused more on Thor's relationship with Loki. I also liked the fight scenes with the Frost Giants, I can actually picture this Thor having an epic battle with the movie Hulk.

I don't dig the Warriors three and Sif. They felt unnecessary and awkward(especially Sif, since Thor already has a love interest with NatPort)
