This one gets under your skin like something laying eggs there. Rin's rented apartment isn't haunted so much as infested, and the film keeps insisting the crawling things in the walls and the crawling things in her head are the same problem, that the spirit bugs are just insecurity with legs. Nothing announces itself. The dread accumulates through hallway shots and the feeling of being watched by a thousand unblinking eyes, until reality and hallucination stop bothering to signal which is which and the talk of cults, street people and a serial killer curdles into something about bodies used as experiments. Yes, the CGI sits deep in the uncanny valley, and the faces move wrong. Half the horror fans who love this movie love it partly for that. Reviewers reach for Perfect Blue and they're not wrong, but this is the smaller, meaner, lonelier cousin nobody talks about.

Rin, a shy and anxious university student, rents an apartment that looks nothing like the bright photos in the listing. The rundown complex is steeped in decay and dread, and she cannot shake the sense of being watched. The streets nearby are no better, with strange street people, odd cults, grisly crimes and talk of a serial killer, while a grinning stranger keeps making his presence felt. Rin begins to sense something darker taking shape, tied to mythology, monsters and medical science. Hoping for answers, she goes to the library and meets a kind young staff member, but what she discovers only deepens her fear. This feature-length horror mystery blends fantasy with mounting dread as Rin fights to uncover the truth and survive.
