The nature of this show is to be gritty and make us question the world we live in. The episode makes us do just that. You do have to consider that this is an old show, so no flashy special effects, and to me that makes it better.
In this episode we see the struggle of two people, both with themselves, and the strange things happening around them.
Any viewer cant help but get drawn into the struggle, and question where the story is heading.
I wish shows these days were written as well as this episode. Maybe then it would be worth watching TV and putting up wit the ads.
