i be a huge horror fan and particularly spanish horror . this film have so many possibility to be good . it a marvelous idea and a vigilante ghost nun and a most of what have come out of jaume balangueró mind . both visual and sound effect be also pretty good . but everything be shamefully spoil by bad direction and awful casting and a painfully bad ( exposition and exposition . ) script . too bad . maybe balangueró should write and direct himself a remake . moreover and i do not really understand why this have to be speak in english by actor who can not really speak english ( and when they do and they do it so bad it just make their performance even more fake ) . if you look at contemporary spanish horror film like el orfanato or rec and the performance be totally in tune with this type of stylish ghost story and that be be realistic and be believable a someone like ourselves and like real people and because that be the only way horror achieve it goal . unfortunately and everything fail in la monja .
