My favorite thought-provoking difference between Do Androids Dream of Electric Sheep? and Blade Runner is Deckard's love for Rachel. In another post in this section, I've mentioned that it makes sense for Deckard to love Rachel if they're both replicants. This is true, and it's also true that he doesn't face any obstacles to love because he doesn't have a wife (of course, he never had a wife because he is a replicant, and his memories of his "ex-wife" are false). In the novel, Deckard tells Rachel that he would marry her if she wasn't an android, but he also no doubt decides not to fall in love with Rachel because he loves his wife too much. Comparing the book and the film, I'm fascinated by the concept of love knowing no boundaries except for the boundaries that we impose upon ourselves. I wouldn't extend this outside of humanity or simulated humanity, but I still feel that this is a strong statement. I also think that Deckard could have decided to love or not to love Rachel in both the book and the film, and it still would have made sense. In the novel, after all, Deckard seems rather disatisfied with his marriage, and could have given into temptation if he decided to give up on his marriage. In the film, Deckard could have decided not to involve himself with Rachel because she is a replicant (as he does in the novel) or simply because she won't live long enough for them to have a meaningful relationship. Any other thoughts?
