Is this movie overrated? No, since Source Code or Apollo 11 American have been waiting for some good sci-fi movie for so long, so after this one come out with a very interesting idea they suddenly really love this one! I watch this movie because I'm Sandra's fans and of course she is so pretty in this movie although her role is just...decent, not the Oscar-worthy one. For me, just my opinion this movie is just some plain survival-adventure-thriller movie which the miracle always came to save our hero. For sci-fi genre, this movie win but for thriller/suspense this movie is kind of fail. We can predict what will happen next because we always saw this type of movie but in different background and I really don't really care or pay attention about what will happen to the character, seriously. Many incorrect scientific accuracy but who cares? It's fiction so just enjoy this. For the exhilarating cinematography and the beautiful Sandra.
