Silversaxophone’s review published on Letterboxd:
Stanley Kubrick is the key influence with its use of natural light and the near hysterical (but superb) musical score. It commits to the construction of the supernatural, and it carefully composes an atmosphere of dread before the shocks start to pile up. However, the psychology of religious mania is subverted by the reality and relentlessness of the supernatural, so it ends up as just another horror film, as opposed to an incisive psychological interrogation of religious belief. It's no Day of Wrath, in other words, but a very impressive and creepy debut for the writer/director, nevertheless.
