This belatedness of the sequel’s future changes the genre of Denis Villeneuve’s new film, Blade Runner 2049. This is not a work of prophetic science fiction. It is an alternative history—tracing out the implications of another timeline. This is perhaps why the layered repetitions in Villeneuve’s film do not build toward a new world, or multiply possibilities forward, but rather double them back, trapping them in an infinite regression of stereotype and allusion.
