Anime aimed at teens is a lot of fun. But anime aimed at an older crowd is on a whole other level! You get more violence, gore, nudity and sex than you bargained for...which isn't entirely a bad thing.
There's nothing wrong with frequenting a slightly predictable, stable anime that has some form of boundaries or limitations that you can count on. But we also need something completely unpredictable, something that doesn't make a lick of sense, because we must feed our desires for the strange.
