Heres an older review taken from my facebook page, the flick is still in theatres though so see it quick.

I had the good luck to randomly ask Danielle to go see this movie last night, we went to go see "Moon" starring Sam Rockwell at the Dark Side Cinema in Corvallis. This movie was a very pleasant surprise. As an independent film I was expecting Moon to have some lower production values, especially in a sci-fi movie that seemed to call for some pretty demanding special effects. Moon's effects were great, the music was the perfect eerie score to help underscore the theme of isolation and mystery and slight menace that permeates the entire film. In the end the music and the special effects would have been nothing without Sam Rockwell's excellent performances in his multiple roles; I cant really go into the details of what i found so impressive or the plot may be given away, but suffice to say Rockwell did an excellent job and turned an interesting yet slightly predictable plot into an intense eerie and sometimes creepy drama. Kevin Spacey also makes an appearance doing the voice overs for Rockwell's robot helper and did a really solid job at it as well.

I definitely recommend that you look up Moon in your area and go see it before it is out of theaters. Below is the trailer for those that are interested.
