How Blade Runner 2049’s world building has its roots in 1982

Most of my discussions about Blade Runner 2049 have been about its gender politics and depiction of women. Specifically, whether it’s deliberately troubling or just troubling. Or a bit of both.

Instead, I’m going to take a look at the storytelling techniques the film uses to establish its future setting. Spoilers will ensue.
