Creates a slow, dreamlike creepy vibe, gradually escalating to a living nightmare. This director doesn't shy away from gore & body-horror. I thought the acting was fine, portraying casually laconic characters gaining gradual awareness of their spooky predicament. I think the hateful reviews are from in cells who are threatened by the subject matter and the fact that it was written & directed by a woman (hashtag masculinity so fragile). The concept is inspirational. I wish this product existed in real life. I want one of these magical safety devices for women. This film will make a nice double-feature with Danny Perez's Antibirth. Six hundred characters seems a bit demanding.
