Austin Armstrong’s review published on Letterboxd:
Rodney Ascher is creating his own genre in the form of horror documentaries. Tense throughout, and incredibly scary reenactments make this by far the most frightening documentary I've ever seen! As someone who has experienced sleep paralysis before, I can tell you first hand it is a very scary experience to not be able to move your body. However I never saw any entities. I would love to hear an opinion from someone that has experienced this how similar if at all, this film is to what they've gone through. Rodney need to make a fictional horror at some point in his career!
