One of the most troubling things about Blade Runner is the rape scene, in my opinion; and I partly think it's a product of '80s star power (i.e. who could possibly resist Harrison Ford's rough and persistent "charm"?). That said, the film makes some intellectual sense if you've read the novel and if you extend the film some philosophical concerns inaugurated by the book. I've always read the scene as implicitly commenting on exclusionary humanism, with "human" standing in roughly for "white male." Deckard doesn't feel remorse over his actions toward androids b/c they're "not human" (which invites a list of objections). Of course, if we really want to psychoanalyze here, it's likely Deckard wouldn't feel remorse anyway, since he's an asshole. The movie suffers from the "Gecko effect"--i.e. that a character is supposed to be someone we don't like, but is presented in a way that elicits our support, as with Oliver Stone's Wall Street (casting Harrison Ford as Deckard is one element of this).
It's really too bad that the film wasn't able to incorporate the serious empathetic reflections featured in the book, but that's one of the inevitable drawbacks of film, so I don't seriously hold that against it. P.K. Dick wasn't the most enlightened person when it came to women, but his novel is far more engaged with what it means to acknowledge others as human than what Blade Runner manages to achieve (in this regard, I'd say that a film like Ex Machina is significantly more developed than Blade Runner).
Aside from that, if we consider lighting, mood, set design, world-realization, and the general vacancy of most (if not all) characters, the film definitely lands somewhere in my top five from Scott. I absolutely love how the film manages to make Deckard look like a hollow, cold, soulless shell while Roy Baty becomes an emotionally conflicted/confused and passionate being. It's an expected reversal for those familiar with the book (not that it happens in the book, but we're better prepared for it), but it's a wonderfully orchestrated shift for those unfamiliar with the original material.
Anyway, I still haven't seen the new one. Been thinking about BR a lot lately.
