Carl Abbot, writing for CityLab, discusses Blade Runner's impact:
Blade Runner fused the images, using noir atmosphere to turn Future Los Angeles into something dark and threatening rather than bright and hopeful. Flames randomly burst from corporate ziggurats. Searchlights probe the dark sky. But little light reaches the streets where street merchants and food cart proprietors compete with sleazy bars—a setting that Blade Runner 2049 revisits. The dystopic versions of New York in Soylent Green and Escape from New York are set in a city crumbling from age and overuse. In contrast, Blade Runner uses the imagery of the future for similar stories of deeply embedded inequality.
When it comes down to it, of course, there’s more fun and schadenfreude in imagining trouble striking a big city than a small town. Terminator 2: Judgment Day would not be half so exciting if T-1000 chased Arnold Schwarzenegger along the banks of the puny Miami River in Dayton, Ohio, rather than the concrete arroyo of the Los Angeles River. In the 1980s, the fictional destruction of New York was old hat. Los Angeles was a relatively fresh target and, for the film industry, a logistically convenient one. Moviegoers were increasingly willing to disparage it, too.
Blade Runner was a catalyst for a dystopian decade that was accentuated by the rioting and violence that followed the April 1992 acquittal of police officers accused of beating Rodney King. Moviegoers would soon get Falling Down, whose filming was interrupted by the Rodney King riots, Pulp Fiction, and Independence Day, with its total obliteration of the metropolis. In print in the early 1990s were Neal Stephenson’s Snow Crash, Cynthia Kadohata’s In the Heart of the Valley of Love, and Octavia Butler’s Parable of the Sower, all depicting a near-future Los Angeles fragmenting into enclaves and drifting toward chaos, capped by Mike Davis’s The Ecology of Fear.
I've got tickets to Blade Runner 2049 already. Can't wait.
