🔍 Search on JustWatch →The film operates honestly within the horror genre: doesn't rush to frighten, lets the space breathe with anxiety. It's about the feeling of wrongness — slow, but relentless.
The film doesn't rush. That's its greatest strength and greatest risk: if you're not ready for slow horror — it will exhaust you. If you are — it won't let go.
For viewers who need sustained tension, not just a collection of scary moments.
