with the participants being murdered in gruesome ways. More recent horror movies challenge more of these tropes. Buffy Summers in Buffy the Vampire Slayer, in the words of Jes Battis, "subverts" the final girl trope of B-grade horror films. Jason Middleton observes that although Buffy fulfills the monster-killing role of the final girl, she is the opposite of Clover's description of a final girl in many ways. Buffy is a cheerleader, a "beautiful blond" with a feminine first name, and "gets to have sex with boys and still kill the monster". One of the basic premises of Clover's theory is that audience identification is unstable and fluid across gender lines, particularly in the case of the slasher film. During the final girl's confrontation with the killer, Clover argues, she becomes masculinized through "phallic appropriation" by taking up a weapon, such as a knife or chainsaw, against the killer. The phenomenon of the male audience having to identify with a young female character in an ostensibly male-oriented genre, usually associated with sadistic voyeurism, raises interesting questions about the nature of slasher films and their relationship with feminism. Clover argues that for a film to be successful, it is necessary for this surviving character to be female because she must experience abject terror, and many viewers would reject a film that showed abject terror on the part of a male. The terror has a purpose, in that the female, if she survives, is "purged" of undesirable characteristics, such as relentless pursuit of personal pleasure.

In Rape-Revenge Films: A Critical Study, Sally Hardesty Sally Hardesty from The Texas Chainsaw Massacre (1974), created by Tobe Hooper and portrayed by Marilyn Burns, has been regarded as one of the earliest examples of the final girl trope. Jess Bradford An early example of a "final girl" can be found in the film Black Christmas (1974), where Jess Bradford, played by Olivia Hussey, is a well-developed character who refuses to back down against a series of more or less lethal male antagonists.
