Among all the tropes, the “Last of a Kind” concept stands out as a rare narrative device that seamlessly blends theme, plot, and character, achieving an almost mythical status with a single masterful stroke. Richard Matheson’s classic vampire novel reigns supreme as its definitive exemplar. ‘I Am Legend (1954)’ is an ingenious hybrid of two previous classics, Mary Shelley’s ‘The Last Man (1826)’ and Bram Stoker’s ‘Dracula (1897)’. Vampirism and plague, a combination that captures the definitive pretext for a last man alive narrative, grounding the myth of the supernatural with the reality of pathogens.

Matheson also deploys another trope in the finale of the story, one that is more devastating in its social commentary. The vampires, the pandemic, and the last man on Earth are just the setup for the novella’s central message, and it’s the one element shunned by all the film adaptations to date.
