Trying my best not to spoil this

Rating: 8/10 (30 January 2012)

Give credit to Moon: instead of hoarding its dramatic twist for the final reel, as a more hackish filmmaker would do with this premise, it lets you know what's going on fairly early on and lets the implications of that percolate. If this makes the back half of the movie somewhat perfunctory, it does show its commitment to big, classical sci-fi ideas, which the 2001 nods are only a part of.
Moon is based off of a series of fantastical conceits, but it's grounded in the world we live in more than many contemporary movies: it's a world of work, exploitation, and crises of identity. The drudgery of life may happen in space now, but it's drudgery nonetheless (here I'm reminded of Alien, another sci-fi classic). It also suggests that we need certain familiar fictions to keep that exploitation going: the loving family waiting at home, the supportive work environment, whatever drops of leisure we can get...
Slickly produced, with a great claustrophobic aesthetic, Moon is a great think-piece film, especially for everyone who's been waiting years for a good science fiction movie.
