This movie is visceral, gritty, graphic. The plot is complicated, intelligent, and rewards the viewer who pays close attention to the film. Unfortunately, the above ingredients probably canceled out the enjoyment of the majority of the folks who rented this flick — after all, we all like a dose of stupidity and a glossy sheen to our horror. Oh, well. If you're still searching for the best futuristic scream-fest since "Alien," look no further.
