Bleach has an excessive amount of filler episodes, making it necessary to have a list of which episodes are essential and which aren’t. As with other long-running anime adapted from manga, Bleach often employed filler to pad the show out. This made Bleach and many other anime like it come off as tiresome and a poor substitute for the manga, which is why one of the biggest draws of Bleach: Thousand-Year Blood War has been that its adapting the final arc of the manga from start to finish without any filler.
