Horror/slasher films typically involve a psychologically disturbed or vengeful male killer targeting innocent female victims. Common locations include dark basements, forests, and victims' homes, and the killer often uses weapons like knives or guns. These films make use of dark lighting, tense music, and unsettling sound effects like screaming to build atmosphere and tension. Editing techniques like quick cuts and fades to black are employed to rapidly progress the plot and keep audiences unsettled.
