This movie should have 5 out of 10 but it's so overrated that I'll give one star.

This is a very long film with some great visual effects but just that.

When you make a movie, specially a sci-fi one, you make a implicit contract with the audience where you say what is possible or not, the problem here is that this contract is broken in the middle of the film, this make people confused about what it is happening. When I watched I have feeling that I was talking with a petulant wannabe- scientific fanboy; there are so many speeches about nonsense physics and poetry quotes that make me sick.

The plot is quite predictable once you are watching it, you will realize what is going to happen. I don't really understand how someone could compare this with 2001:A space odyssey.
