Hey Yakumo, you're right this was damn good.
It felt like a better version of the movie The Inerasable (2015), which was based on a novel by the writer who wrote Shiki. Multiple horrible stories linked to one location, people meeting and interacting through their own journeys were entertaining enough to watch. It wasn’t scary, but also I rarely get scared by horror movies/tv shows anymore. Loved the slow-paced atmosphere, which added to the experience of being akin to reading a book, or reading short Japanese horror stories.
