The script had Kylo not redeeming and being the main villain, it kept Rey as a nobody, it had Force Ghost Luke training her and haunting Kylo, had Finn lead a rebel Stormtrooper revolt, and the final battle taking place on Mortis with Rey getting blinded.
Also has a Sith Holocron proper mashing up Kylos face, so hes forced to wear a mask, like Vader.
Oh and it goes back to Coruscant where the FO has control and Hux is a Chancellir obsessed with Jedi/Sith relics. When they lose he kills himself with Mace Windus lightsaber.
Sounds like a much better script to me. If nothing else, it would have seemed like a more well planned out trilogy. And connected these films to the prequel era in a more natural and less forced way.
