It is kind of funny that the Deckard being a replicant has become the "Han shot first" of this film. Back before the Directors cut, it was actually pretty cool to think Deckard was a rep.
Actually, the “cool” thing is pondering the question and its implications. Less cool is being given a definitive answer, especially one that blithely tosses out the thematic core of Dick’s story for the sake of a cheap, pointless, and pinheaded gimmick.
Seriously, this is one of the reasons writers frequently exhibit a heavy degree of fear and loathing when it comes to having their literary works adapted by “visionary” film directors.
No one is questioning Scott’s directorial supremacy; for better or worse, Blade Runner is ultimately his film. I just wish he’d demonstrated better creative judgement with regard to the “Deckard is a replicant” issue.
The question posed by Dick’s novel, i.e. “When does a human being cease to be human?” is as timeless as drama itself, and the reason the book exists.
The question “When does a replicant cease to be human?” is a dramatic non-starter. I mean, honestly, who gives a ****?
Replicants pretty much are artificially created humans, and therefore are the same as us, but just don't have the same rights to life and freedom naturally born humans do.
Scott would probably agree that replicants are the same as humans.
Dick, on the other hand, would probably be appalled the suggestion.
Again, no one is arguing with Scott’s right to make the sorts of huge, story-shaping decisions contemporary film directors get to make. It is, as we’re so often told, very much a director’s medium.
Nevertheless, when a director chucks a story’s THEME without having anything of substance to replace it with, he does so at his own peril.
The new question becomes do Replicant's have souls like humans do, or do humans just think they do, since replicants can also behave as if they have souls themselves?
A thought-provoking question in its own right, and an important part of the subtext of
any version of Blade Runner. But it is just that; subtext.
I mean, if Scott had really wanted the “Do machines have souls?” question to be at the heart of his movie he should have made “A.I.”
Part of being a good director is knowing what the theme/ counter-theme of your story is.
In a tight screenplay every scene will tend to support that theme/ counter-theme in one way or another. In a muddled screenplay competing themes will cancel each other out, the net effect being a movie that doesn’t know what it’s trying to say.
As beautiful, moody, ambitious, and in some cases groundbreaking as Blade Runner is, it is simply not as strong dramatically as it might have been had Scott been more respectful of the source material (which I doubt he ever read).
I think what frustrates longtime BR fans is the fact that the unicorn dream business is so unnecessary. As you point out, the suspicion that Deckard may not be human (physically or metaphysically) is a really cool question for the movie to raise, and it’s present in each and every one of Blade Runner's various incarnations. Why Scott would choose, via the Director's Cut, to answer the question so clumsily and definitively is beyond me.
