I saw this is the seasonal anime listings and got really hype because there aren't very many horror anime being made any more.
I was really disappointed by the first episode because it actually made me cringe, then burst into a laughing fit.
For real, this anime is unintentionally hilarious.
It has the story telling prowess of a middleschooler who does creepy pasta readings.
Every episode (short) is going to be a new "horror" story reading with very poor slideshow visuals. Hardly animated at all, it's seriously a slideshow.
Music is bad, it's just barely creepy ambiance, and the voice acting is funny, not scary/good.
show is legitimately terrible, it made me laugh, right?
And the episodes are shorts, so I don't feel I've wasted my time watching them.
I'm going to keep watching as this show airs, (I'm writing this as of four episodes being aired,) but I can confidently say that Sekai no Yami Zukan is REALLY bad, and will stay really bad.
