Of all the tropes, the ‘Last of a Kind’ concept is one of that rare theme, plot and character devices that has evolved into a mythical existence with one perfect master stroke. Richard Matheson’s classic vampire novel towers over them all. ‘I Am Legend (1954)’ is an ingenious hybrid of two previous classics, such as 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.
