This is the poorly directed but intriguing story of Sam Bell (Sam Rockwell), the only worker on a moon-based mining station. As Sam drifts into solitude-induced dysphoria, he becomes aware that the corporation that hired him may not have hired him, that his three-year contract might last a lifetime, and that he’s not the only one on the station—or he is the only one on the station, but he’s not alone. The creepy and intriguing premise and the great acting by Rockwell are taken down a notch by manipulative music and thoughtless editing. It’s still worth checking out, but Moon could have been great.
