Writer/director Adam Green's lean suspense story wrings every bit of pathos possible out of a thin, yet terrifying concept. The acting is compelling and the characters are well-drawn, but the real star here is Green. Every horror and thriller filmmaker need to take note of this young man's carrer trajectory.With his third film (after HATCHET and SPIRAL) he has shown a mastery of craft and raised the bar for independent filmmaking. I can't wait to see what this man can do with a budget.
