The previews are misleading because you might get the impression that it's about Sandra Bullock and George Clooney having a series of deep and meaningfuls in space.
It's basically a movie about everything going wrong on a shuttle mission and how people might get back to earth.
This is probably the only movie I have scene where 3D actually supported the storytelling and added to the overall quality of the movie. Very other movie you have seen in 3d will seem half assed in comparison.
Bullock will at least get a Best Actress nomination, this movie should be nominated for best picture. It kicks the crap out of Argo.
