GreatI found this movie a great watch, especially if you're wanting a deeper film, not for a light afternoon comedy. It was gripping and had new ideas brought into the film. Personally I think people are over-thinking this film too much, expecting too much from the director and comparing this film too often to other films like Gravity and 2001: A Space Odyssey. Seen on its own it is a great movie with it's upsides and it's downs just like any other film, but for it's kind, it is right up there in my books. Not one for the kids though, they just won't get it.
