So wrong. Shounen series like Naruto are faitan crap made for a younger audience, there is no exception.
And don't come with FMA as this series is a well written and thought out story above mentioned crappy standard shounen fare.
About your Slice of Life bash, you must be in deep pain, realizing that 13 episode moe nigga series like Hidamari offers as much plot as your 300+ underage faitan with bland underaged emo faggotry characters without personality.
And I'm sure, there are pretty much less adult nerds watching shounen like Bleack, Set Fail or Naruto as moe nigga slice of life comedy shows like Minami-ke, Lucky Star or Hidamari.
So have fun with your shitty series is shitty, instead of reading some good faitan stuff like Blame!, FMA, Shamo, Mirai Nikki, BotI, Berserk or Tsukihime
