Funny that I'd never read this.
The book that inspired "Bladerunner" - the plot - and characters - borrowed from the book, but otherwise completely different entities.
Good. Philip K. Dick is a surprisingly competent Sci-Fi author. Somewhere in my childhood I thought I read something by him that put me off him for life, but that may not have been true.
Anyways, some thoughts and inspirations; not like seeing the film - again, different entities - but that's fair, that way there's no false comparisons.
