I don't like when the hero is the least interesting character(Most Harem comedies, but I guess it's trying to appeal to the everyman here.) If the hero is one of those loud, positive idiots, it annoys me(Naruto, One Piece, Pokemon.) When the fans insist that subs are always better, even if the characters were meant to speak English anyway and the show is funnier in English too(Black Lagoon.) The fans are crap. You watch some anime with your friend, and they have a line of people in cat ears that spout off random phrases in Japanese or want to show you their crappy drawings -more like tracing, how do they manage to screw up tracing?- following them. The 10 year old carrying around a fake id that says 18 so the creator can put their sick fantasies on paper. You're not fooling anyone, you pedophile.
If there wasn't some genuinely awesome anime out there to make up for the mountains of crap, I would kick the habit in a heartbeat.
