I've watched a spate of sexbot movies, and it seems to me that they often want to be a metaphor about how men want meek submissive women and women want to rise up and stab men in the throat. Which is a fine narrative, classic scifi stuff.
But ... it's sort of not a story about a sexbot at all?
It's like when they do a movie "about" genetic engineering, and then a genetically engineered monster kills everyone, and yeah, sure, that's fun, but in no way is this about the actual perils of genetic engineering, nor the steps needed to do it safely, nor the impacts that we would expect it to have on society.
And I'm not sure what I want out of a "proper" sexbot movie/story, but "sexbots are bad because sexbots are people too with their own interiority and dreams and ambitions" seems like a weird and (probably) untrue Aesop.
Maybe the sort of story I'm interested in is a guy who buys a sexbot, and she can be anything that he wants her to be, and for a time this is fine, but there's something about the unreality that gets to him, the way that she'll eagerly agree to anything he asks her to do, the way that he can change her settings so she'll push back against him but then this is just him pulling the strings again. And eventually he wants something "real" but he's had his expectations and thinking warped by living with this sexbot for a year, and there's a series of encounters where it's clear how much he's made it impossible to successfully date. Something about fantasy vs. reality. Something about social drift. Something about blurring the lines that exist in your own mind.
I do generally endorse the credo of "well, if that's what you want to see, write it yourself", and maybe I'll do that, but I think there are a lot of pitfalls, and I'm not in the mood to write something miserable right now.
(One significant pitfall for a movie is that the sexbot is played by an actor, and it's immediately got this veneer of reality to it. And one of the other, related problems, is that if we see something look like a human, we immediately empathize with it.)
