I don't read the manga (so any manga spoilers in tags please, if people wouldn't mind).

Reading it as black-and-white sketches with no voices or moving music or anything like that has never really appealed to me as the best way to experience such a story. The things that the "Sadness and Sorrow" music did for it for example...

I can see why those who do read the manga dislike the anime though, as by the time you've already seen the storyline and the character development and everything else that's awesome about Naruto, all that's left is the reproduction of the art, the animation, the pacing and the music. Usually, there are at least 2 of them sucking at once - the last 2 especially with Shippuuden.
