An excellent sci-fi psychodrama in the tradition of "2001: A Space Odyssey". A couple of things about this movie bring to mind "2001": isolation in space and GERTY the robot. However, GERTY's role is the inverse of HAL’s. If "2001" was about the next step in human evolution, Moon is about human social regression. It could stand as a metaphor for consumerist complacency (particularly with regard to energy sources) in the U.S., fomented by corporations at the expense of disposable workers, here and abroad. In fact, the closing line of the movie indicates that this is exactly what Duncan Jones and Nathan Parker had in mind.
