I don't like the way raene's character is handled, we're constantly reminded of how advanced all sciences are, especially medical, yet that process is identical to current day medicine?
don't get me wrong i don't have issue with gender change whatever being in the story, but in a super advanced sci-fi setting it should be nothing more than a simple surgery (and unlike current day would be entirely functional and be something you could change back and forth with) maybe with a round of pills to help the body adjust to the changes, like they do with augmentation rejection meds in deus ex and cyberpunk.
I have a similar issue with the ferro fluid character from apex legends. it's shown as a future that has little to no discrimination and incredibly advanced science, yet it's somehow brave of the character and they struggled despite the sourced of the difficulty around it not existing in that world/universe, TFTUV's story gives a source of mental discomfort but everything else points towards the science side being advanced enough that it shouldn't need rounds of transitionary meds analogous to the current era
it just doesn't make sense and rips away my suspension of disbelief (a.k.a. immersion if you prefer), replacing said suspension with reminders of all the arguments I've seen with people being complete assholes to eachother (on both sides) for no good reason
