This is based on the short story S.S. by Nathan Ballingrud, but in truth it is based in name only. I don't know if the people who wrote this episode thought they were making something relevant or frightening, but this episode is neither.
The histrionic characters are shrill and unlikeable.
The story meanders from scene to scene attempting to build dread, and then tries to make a statement about...not listening to what people online tell you? Maybe?
