The slasher film girls

The slasher film girls (1980s to today)

Film franchises such as "Friday the 13th," "Nightmare on Elm Street" and "Halloween," the last of which began in the late 70s, proliferated throughout the 80s. Combined, they helped birth the slasher genre, which has continued to thrive.

Many slasher films share a similar theme - illicit sex and drug use among teens, specifically teenage girls. Those who partake in such activities are often met with a violent end (morals!), but not before showing the audience some skin.

The message: Wholesomeness may prevail, but it is not what sells.
