Featuring a terrific lead performance and a compelling science fiction plot, Moon is thought-provoking and memorable.
Sam Bell 1 and Sam Bell 2 (both Sam Rockwell) are different enough to work as separate characters, but also similar enough to be derived from the same source.
The film is thematically powerful, as the best science fiction needs to be.
The opening advertisement for Lunar Industries effectively delivers necessary exposition.
Sam Rockwell is fantastic. The man has never had a poor performance, but Moon is quite possibly his best work.
Director Duncan Jones and Writers Mark Bowden and Nathanial Parker carefully build each revelation, so that we accept every new development.
They make a few minor plotting mistakes, however. For example, when Sam 2 first leaves the space station, we see only one rover. Yet, later he and Sam 1 have their own separate vehicles. How? And why?
Along the same lines, Sam 2 has a very difficult time convincing GERTY (Kevin Spacey) to let him outside, but he and Sam 1 leave at will each successive journey. Also, long range communication is blocked at the station but GERTY manages to have a real time conversation anyway.
That brings me to the movie’s most significant flaw: GERTY. He deflects questions he doesn’t want to answer, lies once or twice, and shows empathy, facts that mean he frequently acts almost human. Yet, Jones and his writers occasionally suggest GERTY is programmed to behave a certain way. It is difficult to imagine a single program explaining all of his actions.
But even GERTY is a relatively minor problem. Moon is very good.
