Does anyone know a good horror anime, preferably made in 2011+?

Pupa looks like it may be good. The anime hasn't aired yet and the episodes are short (5mins). I have read a part of the manga and it's..interesting. Kind of like a guro, except without the sex. The most interesting part of the story is the mc's little sister eating him while he (kind of) enjoys it. Pretty freaky manga, might make a interesting anime.

Hellsing Ultimate is a much watch, if you haven't seen it already. The animation is breathtaking and the fight scenes are intense.

Shinsekai Yori is more of a psychologically imo, but it does have the elements of a horror anime and is tagged as such. Very intriguing plot, although the characters can be a little stiff.
