I had the pleasure of seeing this film this evening.
There are some truly gripping moments, some where you say 'why?' and others where you feel genuinely disturbed. There is an element of 'From Dusk Til Dawn' here where it's clear that one part of the movie has ended and we move on. Initially dark and tense we suddenly see a comedic (to start) element introduced by Don Johnson. After this we depart back into a level of darkness I have not felt since I saw 8MM.
I would recommend that people see this film.
