I've just recently saw a preview of this film in the distributor's little theater. It's a peculiar film; not bad, very atypical for the Mexican industry, with serious flaws but also great moments and incredible acting.
Although is a remake of a cult classical Mexican film, the story takes quite a detour from the original. It intrigued me because it tries desperately to be very commercial and very artistic at the same time.
The premise is basic horror stuff -a suicide anorexic girl is confined in a psychiatric center haunted by a ghost-, and curiously enough, in a few minutes I was completely immersed not in the supernatural side of the story, but in the profoundly human interaction that the plot manages to establish between the characters.
Some aspects of the movie are kind of cheap (al least in front of the budgetary standards established by the pyrotechnical Mexican horror film "Km 31"), but the cast is so great that you forget the economical restraints of the piece.
Mexican actress and -believe me- next Hollywood star Martha Higareda, looks and acts very different from her previous roles (she was always the good looking girl next door), while Danny Perea -the girl from Duck Season-, makes quite an impression as the disturbed and beautiful Josefina, a character that is begging to have her own movie.
I don't have a clue of what are going to think the fans of the original movie, but I can say this: be prepared for a big surprise. You can like it or not, but the movie doesn't leave you indifferent. You really care for this characters... And, by the way, the music of the movie is really beautiful.
