How about a thriller?
I love anime thrillers, they're my favorite kind.
I'm currently watching Hell Girl, and I've already seen Death Note twice, Mirai No Nikki, Terror in Resonance, Attack on Titan, and I do not plan on watching Tokyo Ghoul anytime soon. I want something mysterious, creepy, and suspenseful and not just bloodshed and gore. This is why Death Note has been watched twice.
