How about Mob/crime dramas? A good inappropriate one might be Black Lagoon; that’s the one where, among other things, a couple of the assassins are twincestuous sadistic killers who believe themselves to be vampires, swap genders and identities back and forth (in what seems to be a case of joint Dissociative Identity Disorder) and were brought up being forced to commit snuff porn. Oh, and they look to be around middle-school age.
