If you loved The Blackcoat's Daughter, try Keeper
A bridge between a film you've already seen and one most people haven't. Keeper has roughly 3.4× fewer votes than The Blackcoat's Daughter — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Osgood Perkins, and they both carry the dread, late night mood tags, and they sit in Horror / Mystery territory. If that's the register that drew you to The Blackcoat's Daughter, the second film will land in a comparable space — through a different lens.
What Keeper is
Deep woods. October. A single axe-blow. Newly alone at a rented cabin, Liz expects peace, but finds only a dark presence and signs of former lives. The place has a history; she has a breaking point. Perkins makes horror for people who like to think a bit.
