monkeydelarge: But what else is there?
The reflexion on the borderline humanity of artificial life, the discontinuity between natural and artificial intelligence (strong vs weak AI theory : "if a computer program beats the turing test, is it or is it still not an intelligence ?"), the dick-ian paranoia on the reliability of memories ? It's sci-fi exploring a postulate, with the same issues of life definition and creation responsability that you can find in, say, the
geneforge series. In that sense, Blade Runner is a much more faithful cinema transposition of Shelley's Frankenstein than Whale's movies. Not to mention that these themes hadn't been exploited to death in cinema by that time (but then it got cloned as much as Jaws and Alien, with a bit of the same retroactive consquences).
Makes the film good enough for some people, doesn't suffice for others, I guess. But if you add this to the flawless style and cinematography, it adds up to a total that should count for something, I'd say...
