Blade Runner/Fridge

Fridge Brilliance

 * Perfect evidence for the "Deckard is a replicant" theory: in his job as blade runner, he refers to the death of replicants as "retirement." What does Deckard want to do with his career? He wants to retire.
 * Though given the connotations of the phrase, that could be more Fridge Horror than brilliance.
 * I really couldn't see what was all that great about this movie, the sapient robot motif being done before and this movie's pacing putting me off. What finally got me turned around was that the Voight-Kampff test wasn't just an inverted Turning Test to distinguish Replicants from humans, it was an impartial test to judge human reflex and reaction, and the error margin is present in the Replicants, not the humans. This means that when the machines became more diverse, they became more human than we were, and humanity became mechanical enough to start killing them off to satisfy our own biological security. Not because we were provoked, not because we had some hunt instinct that went askew, but because it provided a more calculated, satisfactory outcome for humanity.
 * Bonus point: Tyrell mentions that the company motto is "More human than human". If that isn't Lampshade Hanging, I don't know what is.
 * The film was one of the first to do the whole robot motif in the first place, so saying it's been done before is an example of Seinfeld Is Unfunny.
 * Take it as a tribute to the film's longevity -- the OP clearly thinks the film is younger than it is.
 * In his first scene, Tyrell declines to take the VK test -- partly to see if Rachel will pass it, but also because he has good reason to fear he might not pass it himself!
