Challenge from the Year 2020

This episode just has a good old fashion sci-fi story that is nicely crafted and delivers on mystery and atmosphere. It's fitting since the mystery of the episode is people randomly disappearing, the events of which align with a sci-fi novel. As such the plot doesn't fully explain the connection, but the tone of the episode just makes it enjoyable overall. Also the Kemur Man is a nice alien design, having some asymmetric facial features that make it quite interesting. I remember seeing its cameo in Ultraman first so it was nice to see where it came from.
