I meant to see this in the theater but never got around to it. We picked it up at the DVD store, and were very impressed by this film. Sandra Bullock pretty much carries the entire movie and proves herself well up to the task. Even if you don't like movies that take place in space (or orbit) the drama here is the thing. Watch it!
Moria gives it 5 out of 5 stars and names it one of the top 10 films from that year. Empire Online says, "Let’s cut to the chase. The simple truth of the matter is you’re going to love this movie. Love it..." Space.com gives the movie high praise and says, "Bullock's performance in "Gravity" is the kind of actor's tour de force that comes along maybe once in a quarter century. Yes, Sandra Bullock is that good."
