6/10 If this is one of the best sci-fi films out there then there's no future in sci-fi (heh). It's OK. Can't really see why anyone would believe they were up there alone, without a team of medics, engineers etc. if not on his base then on another lunar base elsewhere. Couldn't really get to like the characters in any way. Wasn't sure in parts whether I should have been laughing or feeling remorse.
