I didn't know exactly what to expect coming into this movie, other that it was heavy on CG and that it was a sci-fi movie. I was pleasantly surprised to see that it wasn't a "shoot 'em up" movie about aliens (a la "Aliens"), especially since Sigourney Weaver was in it . There is some violence in the movie, but it's not out of proportion, and the graphics are so well done, it's hard to describe. An additional bonus was to watch the entire movie in 3D. This one is definitely going to win some Oscars!
