The reason for the bad naruto animation!

Well considering that over 1/3 of the episodes are filler, its their own fault. And Bleach's animation is consistently good, unlike Naruto's.

Hahahahaha xD No

Naruto shippuden is. A BIG series unlike AOT, FMA,SAO and many more short series,so its impossible for a series of 500 episodes to have every episode an amazing animation,but there ARE episodes with amazing animation like in shippuden:
123,322,204,270,322,329,326,83,85,353,360... So overall there are 20+ episodes with amazing animation .
Proofne piece's animation and bleach's animation = naruto shippuden's animation =reason= BIG SERIES!
Edit:IMO

Yeah i know thats why the animation is lacking in most parts. Cuz its so long, One pieces animation has gone from shit to good to ok to shit. Narutos has gone from great to weird in a few episodes, to ok, to decent, to great , to good, to why, to please, to never again (Pain vs 6 tails) to mediocre, to decent, to good. I dont blame them or hold it against them tho, since i understand that with such a series thats been going on for so long, its ok to cut them some slack.

I hope that sometime in the future they remake the anime with a new consistent animation like Hunter x Hunter 2011. No fillers.
