Do Androids Dream of Electric Sheep? is classic Philip K. Dick, which has never really been translated to the screen well. His theme in a nutshell - what if the world changed before your eyes? What if you are the only person who remembers how it used to be? What is real, your memories, or what everybody else remembers? What if you are the only one who is entirely sane? What is real, your perceptions, or what everybody else perceives?
Ever been in a bar in DC, wall-to-wall D*m*cr*ts, discussing Florida election law and practice?!
I always knew his ideas were great and his storytelling stank. Even when I found out he wrote every story on speed until he finished and never, ever editted his own work, I figured that was pretty obvious (at least, in retrospect). The books of his that I really liked were never the critical picks and vice versa.
But too many other writers, editors, and critics respected his ideas too much to ever criticize him in print, but, in fact, the best description I have seen is that he was just a brilliant a$$hole as a writer.
OTOH, Blade Runner was a truly classic movie. And it was one of the few classics not to be OBE as decades passed. That credit should go to the director!
As an additional point, look at The Running Man, also a Dick plot, much better than the original storyline, but not to the same level of production.
