The strongest point of the movie was really the question of what makes us human. Given that it's stated that Rachael was a replicant, there's the contrast of her character with that of Deckard, who we are led to believe is human.

Rachael, being a human creation, is made to embody what we think makes us unique and precious, the best version of ourselves we could think of. A worthy successor even.

The tension with Deckard is that you have to question if his, say, minimalist expression of those qualities disqualify him as human, even though we know well enough that he's perfectly within the range of human expression in reality, and you would only doubt his humanity in light of the existence of artificial humans who visibly display a greater, more intense range of the human experience than him. Not that they have a choice, either.

Of course then comes the filmmaker to state his intention with it, which takes away the mystique, but eh the artist having a more boring opinion on a work than the people who enjoy it is something that has been quipped about since antiquity.
