I found this episode to be far better than anything in black mirrors most recent season. The directing is masterfully done, the acting is gripping, and the soundtrack is haunting. There is however one way I think they could have improved the story and made it a little darker. In the original short story the reader is presented with the information that the husband is not dead and can in fact be brought back. This would have added an extra layer to the story given that the wife would have actively had to choose to allow her husband to die in place of her just making the decision to not kill the Rex in the television adaptation. I only read it perfect because I could not find a single flaw in this episode and I don't consider missed opportunities to be infractions.
