There are a few things about Spanish and Portuguese supernatural movies. They are usually atmospheric thrillers, slow-paced, causes slow-rising tension, and with truly creepy moments here and there. You won't be seeing too much blood and gore because they are usually not slashers or torture flicks.
Also, there will be heavy nuances of outdated Catholic traditions, especially those related to exorcism, chants, superstitions, and of course, the devil. And usually, the movie is shot in lavishly beautiful and breathtaking rural landscape with magnificent structures. This is true with this movie.
Another similar movie is a Spanish supernatural thriller - The Appeared (Aparecidos).
