are all these reviews of the 3d version? I dont know if Ill ever get a chance to see it in 3d.
I think most critics have seen 3D screenings. But the 3D is not the "in your face" kind, its used more as an additional immersion factor. (an analogy might by HD compared to regular TV)
Many reviews note that it should play fine on 2D.
I'm fortunate to have a 3D capable theater in my town, but I assume it will play on 2D screens as well. (since my local theater only seems to have one 3D capable auditorium) My wife is nervous about 2.5+ hours of 3D (concerned about nausea), so I might go see it in 2D with her first. But perhaps I can still convince her to see it in 3D.

But I will see this thing multiple time, that I am sure of...
