The human body is a fragile system. Horror films graphically illustrate the myriad ways this delicate network of bones, nerves, organs, and flesh can be destroyed. Draining, devouring, decapitating, drowning, and so many other methods that don't start with "D"! It all leads to the biggest D-word of them all...death. And there will be blood. Lots of blood. Heh, heh.
