Just watched this on DVD last night. My comments are about the unrated version.
Basically it's a soft-core video like the kind you see on Skinamax, er, Cinemax. It does aim to be something higher than the typical fare, but it only marginally succeeds. Yes, it is darker and more stylishly lit than most of the other skin flicks. Yes, it has fight scenes and a couple of bloody throat slashings, but for a film trying to emulate the 60's psycho-killer genre or even more precisely, the giallo genre, it was missing something: the presence of the killer. The attacks come out of nowhere. Suddenly, a hand is there, the knife flashes, the blood dribbles. There is no presence, no set-up that the killer is nearby or stalking his victims, and without that, there can be no dramatic build-up, no suspense. And the identity of the killer is way too easy to guess. While most people watch these for the girls, I watch them for the guys, and while the guys here are attractive, muscular and occasionally flashing penii or buttocks (which is appreciated), they look way too similar to tell some of them apart.
A good effort. The director is on the right track, but has a ways yet to go. i hope the film is successful enough to give him the opportunity.
