17. Don't Have Sex, Don't Do Drugs, Don't Drink Alcohol
For some reason, hyper-violent slasher films also double up as morality tales for rowdy, horny teenagers. Hallowe'en, A Nightmare On Elm Street, Puppet Master... These masterpieces of schlock are, in effect, little more than blood-soaked versions of Aesop's Fables. The teenagers that tend to get bunked off first in slashers are those that are behaving in the most hedonistic fashion, as if Jason, Myers, Freddy and company are playing the role of the world's most violent parents. Kids smoking weed, popping pills and drinking the cheapest lager they can find will, inevitably, be sliced into pieces. Then there's always the graphic sex scene, in which the man/woman on top gets stabbed through the abdomen from behind while their confused and terrified partner writhes and screams beneath them.
