Do Androids Dream of Electric Sheep?

The thing to remember is that while Bladerunner is based on this story, it was used for setting and a few of the characters, but a number of the details and plot are loosely used or discarded. However, it is a very good story and it leaves you considering what is real, what isn't, and whether or not that is okay. Deckard and Rachel are about the same as their characters, same with Pris, though the final battle against Roy is not as climactic. We at least get a little more detail of why the world is the way it is, though you don't get the sense of a crowded place. It feels largely abandoned and there are good reasons for it. You do get more of a settled ending here but it also left open the possibility of further writing in this universe.
