First of all, god I am so glad space movies are back. With Sunshine a couple years ago and now Moon, things are looking up for space movie lovers like me.
That said, this is so different than most space movies, being that there is basically one dude in this movie. No big crew of lonely astronauts and their inevitable small-living-space conflicts. No scary aliens. Just Sam Rockwell at his (insane, quirky, bizarre, disturbed) best.
Really unique story. Really nicely filmed. Really creepy, in the best (and not too scary) way.
