I’ve been meaning to watch Moon for a really, really long time. (After all, it came out in 2009.) For some reason, I never knew quite enough about it to warrant devoting an entire evening.

Recently, I saw a list of the top science fiction movies on Netflix. I can’t remember what website I saw this on, but Moon topped the chart. That, coupled with the extra time we all now have, prompted me to finally give it a chance.

At barely over an hour and a half, Moon came in at just the right amount of time. The premise is both simple and complex. Sam Rockwell plays a man in the near future supervising a large moon station that’s responsible for mining helium and sending it back to Earth. He is the sole human in the station, though he does have an artificially intelligent robot called GERTY that is tasked with preserving his health and maintaining the station’s mechanics. Because of a persistent malfunction with the station’s live stream capabilities, Sam is completely cut off from his wife and child. However, the end of his three-year contract is only two weeks away, and Sam could not be happier to get back home. As you might expect, a complication arises, one that threatens both Sam’s homecoming but also the entire understanding of his existence.

Sam Rockwell, who plays the aptly named “Sam,” is always fantastic. I could be wrong, but I think this is the first starring role that I’ve ever seen him in. He is likable, vulnerable, and–most importantly–charismatic. To watch a movie featuring virtually one actor … well, it takes a special person to pull off that role.

I also appreciated the mystery of Moon. A strange occurrence happens early in the film, and from that moment on, Moon keeps you guessing. It’s a quiet movie with moments of intense action, but it’s never boring. The special effects, by the way, are exquisite.

As I said, you can stream Moon on Netflix right now. I’ve read that another movie available on Netflix, Mute, is a sequel of sorts to Moon. I’ll have to check that one out soon and let you know my thoughts.
