How I regret watching this film late at night with the lights off! I think that this may be one of the best Unnerving horror films I have seen. It is not about jump scares per se, or horrifying creatures attacking, but in how it creates and maintains a grounded, unsettling atmosphere. For some the straight forward documentary framing will be take it or leave it, but for me it was essential to making everything in this film feel real and made the tension palpable. This film underscores that good storytelling and craftsmanship can make your stomach turn and hair raise in a far more genuine and satisfying way than most scare fests. All of this is to say, I really hope my dreams do not take me to these empty hallways tonight.
