The original book that the movie got its name from (edit: nevermind, they got it from the burroughs version i talk about below.) It's a totally different story-- one about a national healthcare system that admits people based on some eugenics heuristic, which spawns an underground medical economy with rogue doctors, medical suppliers, and patients who can't go through the national healthcare system because they will be sterilized in exchange for healthcare. it's a really interesting dystopic world he's got there--and I know it because that's all the characters can talk about. They just talk about everything, all the time, like it's a Metal Gear game. I actually put it down halfway through because they just talk about shit non-stop. The world and concept for the story are really interesting, but wasted in an ocean of expository and explicatory dialogue that just makes you want to go to sleep.
I suggest instead:
Bladerunner: A Movie by William Burroughs, which is a screeplay based on the Nourse book (nothing to do with the Scott movie.) It's about half the length, contains all the world building, a 1/10th of the dialogue, along with plenty of Burroughs' drug-induced satirical horror. It's about as obscure and underrated as Burroughs' work gets, but has become more relevant over time, in my personal opinion. It reads like a complete satire of conservative "elderly death squad" nightmares about nationalized health care. It's small, takes about an hour to read, and so damn over-the-top, you can't help but laugh.
