Well whatever the case, the only thing that has bothered me from a filler is Bleach keeping those stupid dolls, even though they aren't in the manga.
Well, the bear (I can't remember his name since it's been that long since they've showed him) serves the purpose of giving some comic relief to Bleach. But the other 3 dolls from the bounto episodes I really dislike. But the point is that they can't just disappear, so the creators of the anime dug their own hole when the dolls were created.
