Tommie Haag’s review published on Letterboxd :
I've said it before and I'm saying it again: Historical settings + horror goes hand in hand. Perfect match. As for the film itself, it's overfilled with white man prejudice (as it should have been back in the 19th century), and I wonder a little bit about what type of true horror they actually are trying to portray here.
Big bonus point for keeping the mystery a mystery for as long as they do in the film.
