It was never reasonable to expect the sequel trilogy to be about the continuing adventures of the original cast. Those actors are way past their prime now, and all of them resented their association franchise and how it overshadowed the rest of their careers, and so their appearances were never going to be more than token fanservice. And obviously there is a degree of self insertion wish fulfillment with Rey, but no more so than with any other action hero, and it's absurd for fanboys to fixate on minor details like how well she can fly a spaceship rather than the actual problem of Daisy Ridley just not being a strong enough performer to carry a film on her own. And Star Wars has always had this problem, due to the insistence on casting unknowns in the lead roles, but at least with the previous films they made sure to give them stronger performers to bounce off of. Ridley just didn't have much chemistry with her supporting cast aside from Adam Driver, and they never went all in on the love story like they probably should have, most likely because they feared too much fan backlash over turning Star Wars in Twilight or something.
