I watched this one today and thought it was good, although the critics aren´t the best ones. It has some lenghts and is not very bloody, but the setting is not bad and it is not really a copy of the endless haunted house movies. What makes it remarkable for me is that you don´t realise from the start, if this is a spanish, US or british horror movie. It first leaves the impression to be a spanish horror movie, but mixed with a bit of Conjouring and the style of Christopher Smiths earlier movies (Creep, Triangle or Black Death).
That I like it is probably also caused by the fact, that I watched dozens of horror-movies, especially spanish ones didn´t expect the style of this one. It doesn´t reinvent the horror-genre, but which film does that nowadays.
