How it could have been better:
1.Just explaining how things work in more depth. The explanation doesn't have to be extremely scientifically accurate or get into too much detail, that's not the problem with how giftias are presented. There just needs to be a believable enough groundwork and internal logic to justify things and solidify them so they don't feel like gimmicks. Alarm bells immediately went off in my head as soon as, "manufactured souls", were mentioned in passing. You have to address the questions people will have.
2.Just don't give all the giftias a finite life span Think about this: what does giving the giftias(replicants) a finite, definite lifespan actually contribute narratively and thematically in Plastic Memories? What is the point? Based on premise alone, this show appears to explore themes related to human and giftia relationships. How would people perceive giftias and how close would they get to them? Giving all gifitias a limited lifespan is not necessary to explore these themes. Bladerunner dabbles in this area, but it is not its core focus. The lifespan of replicants directly ties into its themes. What makes a human human, is it our right to play god, etc., etc. Plastic Memories is firstly, a romance at its core, and secondly, focuses very little on the negative implications of near humanoid slaves. This design flaw only serves to clutter a show with a very limited amount of time to tell its story, but still manages to find the time for constant filler. If the show wanted to focus on the concepts of loss and death of loves ones, it could have just made Isla defective or a prototype . As long as the reason for her dying makes sense within an established framework, it really doesn't matter. This type of solution would both make the show make more sense, and allow for a sad ending. Hell, Isla could have just been a human co-worker with an incurable disease. Check mark check mark, Utsuge.
3.Alternatively, the show could have gone in the opposite direction be emphasizing the consumerism of society. The limited lifespan could be analogous to how to planned obsolescence. If a company can only sell one or two of a product, that wouldn't be too profitable after all. Both Blade Runner and Chobits, especially Chobits explore these concepts. Maybe giftias could be seen as status symbols to show off and replace when a nPost too long. Click here to view the full text.
