The one common debate among anime fans is the quality and importance of filler. Most of the time filler is used in anime not to surpass its ongoing manga that came first so it is used to pad the story out so the manga is further ahead of development than the anime. But when it comes to stories that doesn't have an original source, filler is often used to slow the pace down to let audiences get familiar with the characters and even build up its own lore. But these days audiences want a faster paced story at the cost of character development and world building. So should filler be excluded from all stories if it has no purpose? Or when done right, should it be allowed to stay?
The only time I've had/heard complaints is when the filler is a stretch for time, in which they can't provide character development without the manga's insight. Filler made for that reason, inherently can't have purpose. So it kind of answers it's own question: anything without actual content/progression can be categorized as unwanted. But at the same time, I'm not someone willing to sacrifice character development or world building for fast pacing. They're both undesirable. The handling of character development is most important and should always be present in order to remain engaging. – Slaidey7 years ago
Fillers can add depth to the characters and the setting if they are used right. A filler that does nothing to further develop characters would not please the audiences, so it would be important to make sure that it does have some point about characters etc. It can also be used to smooth out few points that were barely touched in the original works, such as characters that were "forgotten" or provide explanation to some plot elements. In short, the filler needs to "fill" the gaps in the original work. – idleric7 years ago
I feel that Fillers (although some are underdeveloped) can be used efficiently by making the series more in-depth. Not only can the audience see the daily events that impact the protagonist, yet also highlight moments in a Filler's life that affect the happenings of the whole plot. – AnnaliseAtua7 years ago
