Pretty sick and relentlessly grim. Don’t see this unless you’re a true-blue gorehound. Even then, think twice, because it foists a clichéd twist on you toward the end that’s supposed to give it some sort of lame existential cachet. It doesn’t. Your reaction won’t be, “Cool!” It’ll be, “WTF?” Except for the relentless gore, the first three-quarters is a shameless rip-off of Dean Koontz’s novel Intensity. Dean could have brought suit, but after seeing it he decided he didn’t want his name associated with it in any way.
