I’m not saying a Palpatine can’t. I’m just saying within the framework of established rules that it comes off as a lack of care was given to what came before it. Palpatine never had these parallels in the Prequels or Originals. However if they established right away that Rey was her own character with her own sense of self with some parallels to Palpatine then it could’ve worked much better. Like say how Anakin and Leia and Padme and Luke are one of the same. They share many of the same personality traits and qualities but they also have very clear motivations and sense of self. They’re paralleled and connected but it doesn’t stop them from being their own characters. They remain their own people. The same could be said if they showed Rey as a Palpatine from the very beginning and then you find she rejects it all in favour of a different path than that of the Dark Side. She becomes just Rey.

If you don’t have rules within your narrative and story then you create a lack of cohesiveness and consistency throughout the story. The story will eventually run its course and will have nowhere else to go. It’s just as important to respect what came before as it is about expanding upon the story.

That’s the key though as within the fandom it’s okay to pick and choose. There’s no wrong way to enjoy Star Wars from a fan’s prospective. However the fandom and storyteller are separate entities. As storytellers you don’t fall prey to what the audience wants you to make. However it’s just as important to follow the rules of the universe and going from there. It’s about finding a natural progression and middle ground that doesn’t contradict what came before it.
