Basic overview follows.
In 2013, the video game “The Last of Us” was released for the PlayStation console.
It was developed by Naughty Dog, who previously made the “Uncharted” series. Those games are fun escapist adventure. “The Last of Us,” by contrast, made a splash because it was unusually serious.
The basic genre of the game is “zombie apocalypse survival horror.” However, in its details, it’s a little different from the standard conventions. The creatures are not reanimated living dead; they have been corrupted by a fungal infection which destroys their minds and replaces their consciousness with a purely instinctive compulsion to spread the fungus.
The game has a brief prologue showing the initial collapse of civilization, and then jumps forward twenty years, showing the broken world that has taken shape in the aftermath. The basic plot of the game follows an amoral smuggler who is tasked with bringing a teenage girl across the country for reasons that are best left unspoiled.
Critical and audience response to the game was very positive, because the story is much more thoughtful and compelling than was typical in the field. The player is confronted with moral complexity, and is left with troubling implications related to their actions in game.
The game was discussed for screen adaptation almost as soon as it was released, but the game’s creatives resisted the usual heavy-handed tinkering of Hollywood executives. (Stories abound of the dumb changes they wanted to make.)
After a decade of delay, the new HBO series finally brings an adapted version of the game to TV. The primary creative leader of the game is closely involved with the show, and actually directed the second episode. It is nevertheless not a slavish scene-for-scene re-creation; the series (which has so far aired three out of nine episodes) diverges from the source story in the game in various respects, both large and small.
In the broad strokes, though, as an adaptation, the HBO series seems to be using the same narrative framework and pursuing the same thematic objectives as the game.
I am a longtime fan of the game (and an even bigger fan of its sequel), and so far I am quite pleased with the show. It honors the source story without handcuffing itself to its details, and at the same time it seems to be entirely accessible to someone who knows nothing about the game.
