I think people really misunderstand the Rey parentage debate. I’m okay with a storyline that says “anyone can be a hero” but Star Wars has never said that only some mystical royal family can be a hero.
This makes more sense for something like GOT/ASOIAF which pretty much claims only Vaylrian blooded people can ride dragons. Anakin was not born into a royal family. He was born to a slave woman on a planet that was completely unnoticed by the Republic. Padme came from a well to do family in Naboo. While she became an elected Queen she was not born into a royal family. Luke was raised on Tatooine by his Aunt and Uncle, who were farmers who did decent for themselves. The only person who was “born” into anything special was Leia who was raised in a royal family and had the title of Princess.
So literally there is no basis for this “Rey being a Skywalker takes anyway from the meaning anyone can be a hero” That was established in the prequels. Anakin a boy born on a desert isolated planet to the life of a slave was the most powerful force user to ever exist. He was born as “the chosen one” and he’s the definition of a nobody. So this whole “Rian Johnson did something revolutionary” is 1000% bullshit. Anakin was the prophecied chosen one and was born a slave boy. Luke was destined to be a farmer and brought down the entire Empire.
Nobody in the Jedi order’s families has ever been important. We don’t know anything about Yoda’s, Obi Wan’s, Qui-Gon’s, etc family. Luke’s parentage only mattered because it gave him a conflict, to kill his own father or to let the Empire continue. It wasn’t about Luke being some secret Skywalker. This isn’t GOT/ASOIAF, this was about a moral dilemma. It’s not about crowning Luke King of the Galaxy.
Rey’s parentage theories have never been about her being some “royal Skywalker”. It’s been about JJ setting up Rey having a connection to all three members of the previous generation, of her getting parallels to Luke and Anakin. Rey literally was able to grab Anakin Skywalkers lightsaber from Kylo. She was able to fight with a lightsaber and win without any training. Rey having no family and waiting for someone to come back for her was set up. Daisy Ridley was seated between Carrie Fisher and Harrison Ford during the cast reading. JJ set people up to believe she had some connection to the Skywalker family. It wasn’t to make Rey somebody, it was a logical conclusion to what JJ had set up. Rian Johnson went rogue and decided he wasn’t going to follow through. It wasn’t revolutionary, it wasn’t “genius” it was throwing the baby out with the bathwater stupid. He tried to create an argument that Skywalkers were some royal family and you all fell for it. Rey being either a Solo or Skywalker had nothing to do with her being “somebody”, it was about following up on the logical conclusions JJ set up in TFA. Rian shifted the entire conversation about her parentage to make us all seem like we wanted her to be “somebody”.
