“I'm a sucker for true-crime horror and this one hit hard. The historical context makes it even more disturbing than any fiction. The practical effects are gut-wrenching, and the relentless tone kept me on edge throughout.”
“For me, it was too grim without much payoff. The horror is there, but it feels more like a documentary than a narrative. I appreciated the rawness, but I needed more character development to feel invested.”
“The atmosphere is suffocating, almost claustrophobic. It's not a fun watch, but it's compelling in a morbid way. The acting felt realistic, especially the prisoners' despair. Recommended if you like historical horrors that don't shy away.”
“I wanted to like this more, but it was a slog for me. The pacing is slow, and the constant suffering eventually desensitized me. There are a few genuinely disturbing scenes, but they don't make up for the lack of story.”
