What keeps the interest are the obvious homages to the great science fiction films of the 70’s and 80’s. The director cites 2001 and Alien among others in a QA feature on the disk. You know the elements, the robotic helper that is programmed to “save” the crew, the seemingly quiet base located nowhere near anything, the lack of talking, the clear signs of over-stress. Moon just creates these homages empty, not filling in a story.
Moons central science fiction elements are the clones and cloning in the service of lower labor costs. Sterile. But more offensive is that the film doesn’t explore the science or effects of cloning, only gives a surface examination of the psychological effects, and none of the social or political ramifications. That’s why I watch science fiction. Ask an intriguing “what if?” question, then honestly see where it goes. Moon doesn’t even offer a close character study. The clones get over the confusion of there being clones pretty easily, and only refuse to let go of a desire to see the family they know isn’t theirs. Which, what, reinforces the power of love and need for connection? That’d be worse than the nothing. The film does and says nothing.
