This is a super good movie. It's not all fast and actiony but it's quite brilliant. Starring Sam Rockwell and Kevin Spacey as the AI robot (Gerty) on the moon base with Sam. There are no other people there at all.
Sam battles with holding on to his sanity while mistrusting what he has been told by Gerty and his bosses. He is desperately lonely because he has been there for almost 3 years. In two weeks his contract is up and then he'll get to go home.
Unfortunately there is an accident with the machinery and everything goes downhill.
It's on Netflix instant stream. Watch it!
