I'm late to the party but I thought I'd post anyway. Are you still talking about Blade Runner?
I am an avid PKD reader. When I first watched Blade Runner as a teenager (rented on DVD mind you), I didn't think much of it. When I rewatched it, after reading a bunch of PKD and especially "Do Androids Dream of Electric Sheep?", I actually really liked it. My impression is that the movie fails to self contain the theme(s) carefully developed by the novel, and doesn't present it/them in a comprehensive manner.
To begin with, the novel deals with more than just androids. It also deals with beliefs, mysticism, shared and individual empathy and cognitive differences between humans and machines that apparently pass Turing's test. Essentially, it discusses metahumanity and symbolism. Referencing the title, if androids showed empathy, would they dream of electric sheep? Because taking care of animals became a determining symbol of empathy after much of Earth died, and when animals were no longer easily accessible electric animals became the new symbol. In the novel, the issue of whether Rick Deckard is an android or not is only vaguely suggested, by his acceptance of the electric toad, a symbol of either his androidism or his human condition.
The movie strips most of the philosophy and tries to present the aesthetics of a futuristic android hunt. I think it does it very well, so much that, even more so than the novel, it defines elements of the cyberpunk genre. But it is better appreciated if we know what to look for. Mind you, several things are very different. Like JF Sebastian, a character made up for the movie.
It is interesting that Philip K Dick actually liked what he heard about the movie (premiered after his death). After a TV interview where Harrison Ford explained the concept and elements of the movie, PKD wrote Ford a letter sharing his happiness and satisfaction with their implementation of his own kind of futurism. What Blade Runner is about is not only "cyberpunk" or human augmentation. It is also about the projection of human activities of all kinds, imagining what they could become or what they could entail. This relates to art, music, literature, human relationships and, why not, science and technology.
After all, PKD's own brand of sci fi is not concerned with the mechanics or the actual devices. PKD's futurism projects the technology of his time into evolved, elaborate and intricate devices that affect human relationships and perception, and THIS is what he writes about. I think Blade Runner is more about futurism than pure sci fi or cyberpunk, but maybe, regrettably, it is not as self contained as we would like.
