I found the stories on par if not better then Fairy tale. After awhile there is little development and some of the arcs move from family friendly to gresome and dark. Certain developments with minor characters simply sickened me in some arcs made me not want to watch it especially if those characters were favorites.
That all said until around episode 70 the show is an amazing watch. I feel they should have syndicated the series around 100 and then created a sequel.
Until I got to the bug arc which I was extremely disappointed by and then I dropped the show.
