I'm really not that fond of the animation, and find it extremely sloppy at times. However, I simply love the storylines, the only exception here being the idiotic filler arc which was utterly useless. The music is simply put perfect. The show also offers an extremely rich character gallery. I don't think I've ever gotten attached to the characters in any anime as much as in Naruto, the only possible exception here being FMA and/or HxH. All in all it's a really good show that offers plenty of entertainment to me.
