Just got back from seeing it. Absolutely fantastic film, and absolutely fantastic acting from Sandra Bullock. It's gorgeously horrifying.

It's the first I've ever seen that uses 3D as an artistic tool and not just a gimmick. This movie was made to be seen on the big screen, in 3D, and it wouldn't be the same experience without it. Anyone who goes to see this movie, SEE IT IN 3D! It really was made to be viewed that way. I remember one scene was so well done with the 3D I actually flinched when the stuff came flying toward me.

It completely deserves all the praise it's getting, and Sandra Bullock deserves any awards she wins for it. Bravo.
