Why exactly do you hate the series so much, Kuro? There's good world-building, highly varied characters, moral quandries...
Because as far as ninja series go, I'd much rather watch Ninja Scroll, Ninja Ressurrection or Basilisk.
Not only does the loud attention-seeking hyperactive ninja in a bright orange jumpsuit piss me off to no end, Naruto is also responsible for the fandom of thousands of annoying brats everywhere. Seems like everywhere I turn, I have to run into a retarded kid with a bandana.
And those guys aren't ninjas. In fact, they're anything but. "Ninja" in the Narutoverse is the equivalent of "Wizard" in D&D, and that pisses me the fuck off!
If they'd only gone with calling them anything else (hell, invent a term for them), I'd find it at least tolerable.
But noooooooooo.
Ninjas do NOT dress in bright, cheery colors.
Ninjas do NOT carry katanas, much less buster swords.
Ninjas do NOT hadouken the shit out of forests.
Ninjas do NOT wear identifying marks of any kind, MUCH LESS ON THEIR FUCKING FOREHEADS.
Ninjas do NOT carry cellphones.
Hell, Flame of Recca is a much better ninja series. It has just as many moral quandaries, a rich inner mythology all its own, cooler fight scenes, and a protagonist that IS AND ACTS LIKE AN ACTUAL NINJA.
Plus it has dragons. And the dragons are fucking badass.
