Brilliant, borrows from other space movie themes, but the final product is gold. This is a movie with basically one set, and one main actor with the voice of Kevin Spacey as a computer that will remind anyone that saw 2001 a Space Odyssey of a sane version of HAL. The moon is now used to harvest Helium 3, it's mainly automated, with one man overseeing the operation with the assistance of the base computer/robot. Themes you will notice borrowed come from Outland, Blade Runner, 2001, but they manage to put a spin on the plot that is unique and that keeps it interesting.
This is a psychological drama, it is not an action movie, it is not a date movie, this is the sort of movie you probably will get the most out of if you watch it in the dark by yourself without interruptions. The mood needs to build in order to get the full effect of the script. Suffice it to say that all is not what it seems on base, and our main character starts to feel a bit stranded on the moon, wondering what will become of him. He gets help from the most unexpected of places, but is it too late? You can't really describe this movie without giving away essential plot elements that are better left discovered by the viewer by watching it... which is what you should do, this is a great movie.
