Dirk Diggler’s review published on Letterboxd:
A stunning, mind-twisting psychological thriller that's definitely the most scary and disturbing anime i've seen. It makes full use of the medium, it simply couldn't be done to same effect with live action. The soundtrack is perfectly used to create an unsettling feeling, the social commentary and themes are interesting, and the editing has to be experienced in order to be believed. That ending! Hard to believe this was a debut.
