Especially from the aspect of enjoyment this show is real hell. Every single episode presents an enclosed story where we can ALWAYS see new characters that can be right away fitted into a pigeon-hole of a victim and a villain, and that ALWAYS evolves according to the same pattern. In the end, Enma Ai Jigoku Shoujo intervenes like "deus ex machina" to resolve the story saying ALWAYS the same phrase. Since this pattern never changes, it becomes terribly boring after some while, regrettably, we are to suffer it to the very end, because of the absence of any continual story. Moreover, we don't learn anything much about Enma Ai, nor about her partners from the hell ride. The animation itself is very good, as well as music by Takanashi Yasuharu which is well worth listening to. Weaker characters that can be driven crazy by boredom from the monotony are not recommended to watch it.
