ALL SHONEN JUMP FIGHT SERIES GOES DOWNHILL, EVENTUALLY.
Protip: /a/ still loved Naruto while the filler season was going. Are you new here? Naruto going downhill had nothing to do with it. Naruto became the most popular animu in the history of America. Some reruns of Naruto received 3 million+ ratings. Which is more than every show in this current season combined.
/a/ didn't want to be associated with a mainstream show like Naruto. They couldn't be considered elite animu fans if they were caught watching a mainstream show like Naruto. Naruto has the ability to attract newcomers. This is common knowledge. Naruto is much more popular than Bleach, One Piece, Rurouni Kenshin, Yu Yu Hakusho, and DBZ combined. Naruto must be doing something right if it has the ability to attract so much newcomers. Naruto even managed to increase Cartoon Network's kids and teens demographic by 30% (making Naruto the number 1 show on cable TV for that demographic).
Why can't /a/ learn to accept the fact that Naruto attracts newcomers. Back in our days DBZ use to be the number 1 newcomer magnet. Nobody insulted me for being one of the 700,000+ newcomers to be attracted by DBZ when it reaired on Toonami in 1999.
