I mean Naruto as a manga has a lot of storyline to it. wouldn't it take a while for the anime to catch up to to the manga without fillers? If so, why do they continue to create them? Why not simply take some liberties with the manga's story and flesh out some of the condensed areas to add episodes here and there?
In an anime like Bleach I can understand why you need fillers (even if they suck ass) because Bleach's storyline goes absolutely nowhere for like 60 f'king chapters at a time!
Anyways just asking.
