I'm a big Junji Ito fan, but I haven't really found any good anime that come close to matching the creepiness of his manga stories, including that one Junji Ito anime series that's out there. I think the closest I've seen is Mononoke, though honestly I haven't seen a ton of anime, so maybe I'm missing something. I thought I'd ask to see what you all might suggest in terms of genuinely creepy/unsettling/dark anime movies or series, either similar to Ito's stuff or whatever else you think is good.
Any suggestions?
+1 for Shiki, one of my all-time favorites. It's what you get when you make an anime from a real book instead of a light novel.
