If they could animate more of Sono Hana, that'd be beautiful! *_*
I wanna see a hentai animes for MinDeaD Blood and Gore Screaming Show. Guro is a bit niche, but I think it has potential!
Saya no Uta is one of my favorites. I want to see it as an OVA, but as a psychological thriller I'm not sure if they could pull it off well without the internal monologue. I saw this happen with Higurashi. I liked the Higurashi anime, but it could have been much better than it was considering the source material. If they can pull off, it'd be outstanding!
