What do you think horror is?
It should make you squirm in your skin. You're mind should go mad at thought of what could be.
Not this stupid slasher shit. "OMG drive even though the bad guy running on foot is faster than a car."
Idiots.
The mind is much more interesting place to play with than a humans gag reflex at the site of mangled bodies. The imagination is much more powerful than we give credit.
