Unlike myself, who rejects e.g. Madoka without watching, Nova gave penguins a try:

Where a shitty shoujo show pretends to be a humorous, thoughtful and dramatic noitaminA show. The bipolar on-off-drama is complemented with the incestuous dynamic duo of a girl with a dick and the Shoujo Male Crush Archetype A-563. Also features Rez, though I liked the game more when it wasn’t about two boys plotting to put the meat to their half-dead sister.

The widespread adoration of these shows clearly shows a predilection towards the disturbing among a sizeable chunk of anime watchers. They may even command the BD market.
