Nighty Night and the Peep Show
If you enjoy black humour, then you should like Nighty Night and the Peep Show. That's something I heard about these two British dark comedies that premiered in 2004. After watching the first seasons of both shows, I did enjoy one, which was was the poorly named Peep Show; it's poorly named not because it doesn't fit the comedy, but that it's hard to discuss a show called the Peep Show without raising eyebrows.
So why does one work and the other does not? The Peep Show is not as dark as Nighty Night, so that may be one reason, but the more accurate reason is that the show's writers don't ask for the viewer to laugh at sociopathic behaviour. Nighty Night is not about humour so much as it's about framing despicable acts as humour. The marketers of Nighty Night compare it to Curb Your Enthusiasm,which is unfair to Larry David's show as it features no character I would consider sadistic.
