I liked the aspect of the force being more democratic and mysterious and its choosing a neophyte no one to restore the balance. I liked that Last Jedi basically made the whole mutant inherited bloodline thing, irrelevant. Only for Rise to make Rey a Palpatine and undo the idea of Star Wars going back to the style of the original where Luke was a no one, who had the courage to leave Tatooine and confront the Empire. Originally Luke was a brave kid who went on an adventure he wasn’t the son of a super-villain/mutant with the most mitochondrial DNA or midichlorians whatsits in existence to some prophecy. Its undermines the force and free will. Its junk.
Luke was always the son of a Jedi. Jedi didn’t start out being monks. That is a prequel thing. I think it is important to see both that any old nobody can be a Jedi, and that the force can run strong in a particular family. Anakin was a nobody. Luke was his son. Rey is Palpatine’s granddaughter (or daughter of his clone). Nothing can negate that Anakin and broom boy are nobodies. Most Jedi came from nobodies because the prequels made them monks - no attachments means no kids so no Jedi bloodlines. So there is a lot more to the saga that says a no-one can become the chosen one than that you have to be part of a bloodline.
