To be honest, I have never seen or read the original story. Maybe this is a good thing, I don't know. As far as I can understand it gets the basic idea and only harshly does it re-make previous versions. Performances and film pace is overall OK. No stupid subplots and all, even some smiles raise from time to time. Due to some erotic scenes involving prostitutes, it can easily be characterized sexploitation, and as far as erotic stimulation is concerned, it scores quite high. Moreover having Anthony Perkins starring in it, it could easily be loved by horror completists or cultists. All in all, I had a nice time.
