Well if Deckard isnt a replicant, he really wasnt special in any way. Wallace only wanted him for whatever knowledge he may have of what happened previously. He isnt some key to the destiny of humanity.
We've kind of always knew Rachael was special in some way, Tyrell even said she was an experiment.
I dont see it really changing much about the characters or what happened unless you blow it out of proportion. I think Wallace hinting to Deckard that it was all destined to happen and was orchestrated was him just screwing with Deckard to get what he wanted. The fact that he went through the trouble of making a fake Rachael for the same purpose is proof of that.
I thought once Wallace had Rachel's bones and was able to create another Rachel he needed Deckard because his seed might have somehow been special.
I still didn't get if Deckard was or wasn't a Replicant.
Wallace says to Deckard "... how instant your connection. Did it never occur to you that's why you were summoned to her in the first place? Designed to do nothing short of fall for her right then and there. All to make that single, perfect specimen. That is, if you were designed,,, love... or mathematical precision... yes... no."
Deckard responds "I know what's real." then has a pained, confused/conflicted expression.
Overall, it wasn't bad. I was surprised that either I managed to avoid the spoiler or they didn't make it public that Gosling was a Replicant. It was revealed pretty quick into the movie. That changed my perception quite a bit. I don't think Gosling is much of an actor so I credit the casting director for knowing how to pick someone that has a very vacant, empty "style" of acting. In other words, he makes a good Replicant. It's too bad Michael Fassbender already played an android because he could have nailed this part as well, although he's not as boyish.
The story, given enough thought, can probably be torn apart pretty easily. I'm not sure why all the trouble was made to hide their child. Was anyone really hunting them? Could they not have gotten far enough away that nobody would have bothered them? Or was it that once she was pregnant they both knew something bigger than them was happening and that their child was somehow important. Yes, a Replicant giving birth seems pretty special... but was it an anomaly or by Tyrell's design that she be able to procreate? If it was intentional, why wouldn't he have sent that model off world to procreate without fear of being hunted?
That raises a question that would be worth seeing in a third movie.... what IS off world? If they have terraformed and colonized other planets, why do they continue to stay on Earth. It seems like a mess. K didn't get too far out of LA and was shot down by wastelanders. What's the rest of the planet like? Just as messed up?
I was about as disappointed as K when they said he wasn't their child.
Were the rogue replicants the last others he was hunting?
I was also hoping that Joi the hologram was actually going to be real and guiding him or would be the child or something. It was sad when Luv breaks her device... and when he sees the advert-hologram.
I also didn't understand why either side (human or Replicant) knowing that a Replicant had been able to get pregnant would cause a war. If they had to be impregnated by a human male... wouldn't it mean they could live together? Or was the issue that they were always created to be slaves, and it would free them of slavery because they had "souls" and weren't just products?
Just some after thoughts... I'll have to process it a little more.
