What the hell were the screenwriters thinking?
The movie starts off reasonably well but then becomes ridiculous in its cliches. The slut, the pothead, the eeeeeeeeeeeeevil businessman, the repressed assistant, the left-wing Rage against the Machine wannabe, the alpha female, the big dumb jock, and the working class hero. Can you say cookie cutter? The inital scenes where the demoness appeared were creepy enough. Then the movie went majorly downhill with the H P Lovecraft ripoff and the ritual to bring evil to life that apparently can take place over the course of a century. As if that weren't enough, the screenwriters felt the need to throw in banal dialogue and seemingly interminable discussion scenes about the nature of zombies into the middle of so-called action scenes. The ending was predictable and cliche-laden as well. I'm not really sure there was any potential in the storyline, but whatever there was never got a chance to breathe from this supremely amateurish effort.
Carthago delenda est.
