Because if you ever watched the bleach anime it caught up to the manga and was promptly cancelled. It's so they can properly make the anime episodes as close as they can to the actual manga.
all fillers are dumb, i dont know why they even bother to make fillers.
i hope instead of making a filler they would just take a season break or something.
these fillers give bad name to the actual series among the people who dont read manga or are unaware of manga.:nuts:
