Since its origins in the mid-1970s, the slasher has been defined as a subgenre of horror in which a serial or mass killer stalks and massacres middle-class youngsters, and preferably attractive young women, using cutting weapons or projectiles. In that regard, the twenty-first century has seen a revival of the slasher, combining the release of original movies with remakes of classic films, adapting the traditional plots to the current context. In this paper, a comparative content analysis is performed on 13 slasher films made during the 1970s and the 1980s and 13 remakes premiered in the new millennium, focusing on the differences stemming from the adaptation of the latter to the new sociocultural context. The results indicate that, although there have been a number of changes, such as higher doses of explicit violence and profanity and in the fight responses of the victims, most of the subgenre’s defining traits have remained intact, whereas others, such as those relating to the defining traits of the victims, should be questioned. The limited differences found between the original films and the remakes provide the basis for drawing interesting conclusions about the subgenre itself, as well as to raise discussions about the different contexts of production and reception.
