Which episodes in ‘Naruto’ are fillers?
One of the apparent benefits is that it should make the show more marketable in countries where anime is generally unacceptable length for children (such as American television). This way, new episodes can be included with some filler storyline to lengthen the story arc.
Fillers are most often a narrative device used in shonen manga and anime series to create gaps between events at which new publications will appear. While they may seem pointless or superfluous, fillers serve an important purpose – they give animators and writers time to produce what would otherwise be a very quickly airing show uninterrupted by breaks due to holidays, writer’s block or other delays typically encountered when creating such an episode-long work.
