Retrofitting Blade Runner: Issues in Ridley Scott's Blade Runner and Phillip K. Dick's Do Androids Dream of Electric Sheep?
From dust jacket: Blade Runner's richness and fundamental  integrity will continue to fascinate viewers for years to come. Its  implications as a thought experiment provide a starting point for  urgently important thinking about the moral issues implicit in a  hypertechnological society. Yet its importance in the history of  science fiction and science fiction film rests equally on its  mythically and psychologically resonant creation of compelling  characters and an exciting story within a credible science fiction  setting.
