This film is Science Fiction. Let me repeat..SCIENC FICTION. I thought it was entertaining. However, I see other "critics" basing their opinions on the fact that this film was too fake, bad science. Seriously? Look, if you look for realism in film, stop watching film. If you look for realism in science fiction films then don't watch Alien (or it's sequels), Avatar, Terminator, Ghostbusters, 2010...in fact, stop watching science fiction movies all together. Read biographies. My opinion, this movie was entertaining. Nothing more. A good time waist like any other science fiction film. People have to stop looking into syfy for some deep meaning or realism otherwise it makes no sense to even watch them. They're not called science fact films people. It's about imagination.
