About
You may enjoy this if you like low-key, cabin-set sci‑fi thrillers with a creepy mystery vibe and some ambiguity, similar to Demonic; Not for you if you want fast pacing, clear answers, or big scares.
Pros: eerie cabin atmosphere; intriguing sci‑fi mystery; some strong acting | Cons: slow middle stretch; uneven writing; unclear, divisive ending
