The Blackcoat's Daughter ★★★½

Extremely well-directed, with a shockingly great performance by Kiernan Shipka. This would be a 4+ star film except I saw the "twist" ending coming from a mile away, which for me hurt the pacing of the latter part of the movie. Still, my favorite Satanic movies are the ones that tell quiet little stories of madness, and this definitely qualifies.
