Filler still filler and don't call other people " stupid" or "retard". Reported
IMO, certain Episodes elaborate further on what took place in the Manga because the Manga is limited. Since we have the luxury of seeing it literally frame by frame instead of every other second/minute based frames I personally, as well as a few others would consider it to be cannon. Why? Because it's actually directly legitimate to the story line simply because it's in reference to the skills or information that already exists and that is in fact true.
Now if we're talking about actual fillers that have no direct reference to the Manga/Story line at all... then I can agree.
