If you glanced at what's come out in the past 20 years, you might think it's the amount of diced body tissue flying around the screen. Horror has always depended on shock value, but what really unsettles us hasn't changed much: an ominous sound from around the corner, an indecipherable figure in the distance, a sense of impending doom as somebody opens a door. Gore has its place, but only when it's attached to an idea. Hostel is less a spine-tingling chiller than an endurance test for ick along the lines of E!'s Botched.
