The breakdown: A lone astronaut has to take care of himself on the moon's surface as he's on a three year job to send back pieces of a power source that powers planet Earth.

I had never heard of this one, and was pleasantly surprised at how engaging it was.  It's a bit of a mystery in some places when strange things start to happen, but it's interesting to see how it all turns out.
Sam Rockwell plays an astronaut that works alone, except for his helpful computer, in a tiny station on the moon's surface.  His job is to collect and send back pieces of an element that powers planet Earth.  His job is to survive 3 years alone on the moon, and then get back home to his family.  He gets recorded messages from them and it seems to keep him going, but he is certainly eager to leave after his three years are up, and he's approaching that time limit within weeks of the movie's opening scenes.
Unfortunately, he suffers an accident that renders him unconscious when he's out in his rover away from the station and then things start to get strange.

I certainly don't want to ruin this one for you, so you should see it.

4 out of 5 for being an original and entertaining story.
