This is one of the most boring, slow, annoying, painful to watch, twilight zone episode ever.
A dentist who is having a hard time decides to kill himself but is saved by a tooth fairy who is in charge of taking care of distressed dentists. Well, that's not the kind of story I enjoy. But nothing interesting happens here, nothing exciting, nothing! This episode has a stupid ending too.
You don't feel compassion for this guy, all you want him to do is to stop whining and get devoured by a huge octopus or some creature. That should really make this episode interesting but it doesn't.
