The biggest reason I still watch Naruto is because I want to see it end. Reading the manga is fine and everything, but I like to see things animated. Even if it means sitting through filler and fluff. I've gone on two Naruto manga binges before because I was fed up with the anime, and I'll probably do it again, but I'll still watch the anime. I can't just drop something I've been doing for... how many years has it been now?

Though I do agree with what other people have said about the series and why it has been going downhill (especially the "getting older" part).
