slasher film

A slasher film usually refers to a cheaply-made sub-genre film (usually in the horror genre) designed for the teenage audience (teen movie), deliberately made to contain gory, blood-splattering, explicit deaths without any build-up, style or suspense, often committed by an unstoppable serial killer, with a sharp bladed weapon. Most slasher films are created to generate sequels and repetitive boredom. Also known as "splatter films." See also "trash film," "grindhouse film," "schlock film," "B-film," and "Z-film."
