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?
The Higurashi VN has its first chapter free in Steam, by the way.
