Superficially, Todd Strauss-Schulson’s The Final Girls looks like what would happen if Friday the 13th got the Wes Craven’s New Nightmare treatment: It’s a self-referential exploration of tropes (it takes its title from scholar Carol J. Clover’s brilliant analysis of horror cinema), a genre-excavation using a movie-within-a-movie conceit. (Note that the film-within-the-film is not Friday the 13th exactly, but the very similar fictional ‘80s horror hack-’em-up Camp Bloodbath).
