Neil Bahadur’s review published on Letterboxd:
A work almost too disquieting: Procedural pushed to obsession pushed to psychosis. Starts as a seeming vision of 90's Tokyo as a city of corpses and interrogation rooms, but even as it does work on sociological levels, (similar to Pulse, Kurosawa uses genre trappings to have us reflect on present spaces and objects) it's a film of the psyche first and foremost. I can't think of a movie that feels more scarring. Even reflections on voyeurism & cinema: by desiring to understand evil we risk getting to close to it, and if we get too close to evil we will become evil. Even as we travese physical spaces we enter psychological ones, like Mamiya's cell or the abandoned house. And when these spaces intercut, even a cup of water is terrifying.
