Jigoku Shoujo (Futakomori)

I'm currently re-watching the series. The first season consists of 26 episodes and the second season is ongoing. I believe the title literally translates to Hell Girl. I personally hate it and love it at the same time. The first huge chunk of season 1 is highly repetitive. At this point on, there's a different story or plot every episode. The story DOES move on later in the series. And, yeah, this isn't one of those feel-good anime >_>; You should kind of notice that after watching the first ep of the first season.

Part 1 of Season 1 is usually made up of one shots but then the Part 2 of Season 1 is (when Tsugumi comes in) is a rensoku anime. Then Season 2 is a continue on from that.

Yeah, season 1 is too repetitive, and I felt really bored before the ending made my impression became better back. the season 2 seems more better, cause its starting to expanding the characters.
