I saw this film alone in a "house container" in the middle of the night, during my 24H shift as the radio Duty Officer in a UN military camp in Eastern Africa. Maybe that's why it made such an impression on me, partly, anyway!
Whatever the unusual setting for viewing it, it must be said I'm a long time fan of Clive Barker and his universe(s), and that that of course helped in gearing up my imagination. In my opinion, the special Barker trademark, namely a mood of overwhelming and insanity-inducing Biblical horror, translates well to the screen in this film. The protagonist, played by Sheffer, remembered from another Barker movie, Nightbreed, is caught in a web that seems impossible to escape. Even though he's a real dumb b*****d, you just can't help feel a little sorry for him; the way he is manipulated by gruesome, hellish powers is almost too much. No way he can experience what he does without loosing his mind!
The acting isn't anything special, but I tell you, if you are capable of living yourself just a bit into the story, you'll feel like I did: That movie has warped my fragile little mind!
Advice: see it alone, tired, just before you are going to sleep, and with your senses alert to begin with - and you'll be ready to continue the roller coaster ride in troubled dreams afterwards. Disturbing! 7 out of 10.
