be this a horror or a psychological thriller . to me this be a curious study of lust and betrayal and death . the true story be often abused term in movie making . only and this time there be no abuse and just artistic freedom . enjoy amazing scenery of a spain in 1800 and the symbolic detail that all have their meaning represent the hand and the bird and the nail . the horror be there but in a subtle form and the visuals be very delicate . however and it seem to me that a lot of horror fan be put off by the fact that this movie be a slow pace one . yes and it might not scare you even once but it doesn not matter . this time you will be absorb by the story with amazing visuals and strong cast that turn this movie into a work of art . if you want something unique a an underrated horror movie worth use for study of photography look no far . base on that fact alone it worth positive .
