The Rise of Skywalker should have doubled down on the creative choices of The Last Jedi. Rey should have started training a new set of Jedi, but these Jedi would have been different. Akin to the Protestant reformation, perhaps. Also, Finn should have been Force sensitive. Armed with Jedi skill, he should have incited a Stormtrooper rebellion that proves a key factor in overturning the First Order. None of that Palpatine returns nonsense should have happened. I'd have kept Kylo Ren as an unrepentant villain to the end, despite his soft spot for Rey. I might even have ended the film with the fall of the First Order and the capture but not death of Kylo Ren. He would have to answer for his actions and be imprisoned, but perhaps Rey goes to visit him. That would have been a radically different ending for a Star Wars film, I know, but I quite like the idea. Also, the original idea of having Luke appear as a Force ghost to Kylo Ren, tormenting him, was brilliant. I wish that had been followed through.
