I already said I wasn't watching the filler but from what everyone so far has said is: poor animation, poor outwork, most likely been outsource to cheaper foreign companies*, copy paste images scene and animation and story as well, and also a story that you can find older version of on fanfiction sites. Everything about this filler says their going on the cheap for this filler arc. Either it's to save money until they can get into the bolt series, or they can't afford to do anything other then this.
*sp is know for doing this http://tvtropes.org/...r/StudioPierrot Creator's Favorite: The staff from the studio unapologetically admits that they're big fans of Hinata Hyuga from Naruto (via interviews and an Omake in episode 165) to the point that they gave the franchise's creator a draft for a movie that would focus on her love story with the titular character!
Off Model: Due in part of making long runners, with many episodes of said shows (Naruto especially) wholesaled out to sub-standard South Korean studios (namely NARA Animation Studio))There was another comment on their that got deleted that said something along the lines of. "This is so common and happens so frequently that fan knew which company did which scene (they outsource to apparently several Korean teams) they outsourced the anime to depending on the art work."
