the series really fell apart after they saved Rukia. it suffers the same problem that most shounen anime dose with powers levels being up the ass and having a bunch of interesting characters being left out because set power level being too low or being killed off way to quickly. drop it at the beginning of the quanciy arc since i lost interest. still remember liking alot of the filler arcs too give the lesser impotent characters a moment to shine on screen. like the vampire one or where their swords started too rebel. it was interesting seeing the characters interact with their own powers and having some character building.
