I'm, primarily, writing this review, in order to warn other viewers, and prevent them from wasting their time with this episode.
"Room 104" is a decent anthology. However, one of the bad things about anthologies, is that you may end up with some dud episodes. This is one of those episodes.
After about the first five, to ten, minutes, I began to wonder if I should just shut it off. This is because it started to seem as if this was just another one of those abstract episodes that don't amount to anything. It wouldn't be much of an exaggeration to say that I've watched music videos that have about the same amount of substance as this episode.
I won't give away spoilers. However, if you were to read the synopsis, then that tells you all you need to know. This is because, this episode, literally, doesn't have much more to offer than its basic, single-sentence, synopsis.
