This show is nightmare fuel, pure and simple. This 'nightmare fuel' aspect is, in no way, a negative view of the show. The backgrounds' dark and dreary art style seems to compliment the characters' lighthearted antics. Oftentimes, extreme reactions in the characters faces are grossly exaggerated in a vividly horrifying, and wildly entertaining, manner. The story lines, and even the setting, are twisted and sometimes hard to follow. Again, this is not detrimental to the show's entertainment value, but instead enhances it.
