Title says it all, the sequel trilogy had some moments, but overall was not great..So let me know how you would have changed the films. For me it might all ready rubbish, but how I would have changed thing
Force Awakens:
Rey is not a no-one, she's Luke's daughter which is why his lightsaber reacts to her and her natural ability in the force is through training. I would have her been at the Luke's academy training and survived its destruction. To protect her Luke wiped and slightly altered her memory and left her on Jakku. The Falcon is there because he knows eventually she'll need to leave and he wants someone to be able to find her, i.e. Han and Chewie. Oh and Han and Leia are still married, Han is just doing is own thing at the moment, while helping Leia with the resistance. Han does not die, Kylo goes to use the lightsaber but something stops and merely wounds him. Finn fight Ren and gets close to beating him, before Ren cheats at which point Rey calls the lightsaber to her and surrenders to the call of the force that she has felt since she first touched the lightsaber. Beats Rens and is left wondering why she was able to do so. Then she, Han, Chewie and R2 go to find Luke. Film would end with just a voice (a familar voice to us) saying 'everything has proceeded as I have forseen it'
The Last Jedi - Luke doesn't toss the lightsaber away, he hands it back to Rey and walks away. Conflicted he agrees to re-train Rey, but doubts himself which causes her to touch the dark side and heads off to find Ren taking the Falcon with her. R2-D2 is left behind and Luke is left wondering where he went wrong again. At this point R2 plays the original 'Help me Obi-Wan Kenobi message' which reminds Luke of how he was, then a 2nd message plays but this is his father and mother recording a message to their child, how they hope for brighter future for them and they only want the best for them and hope that they will forgive for any mistakes they have made. At this point Yoda shows up and tell him that its through failure we learn to grow. This makes Luke realise he's been hiding and he takes his x-wing and goes to find the resistance. At this point I would imagine the film takes a similar path, except Snoke doesn't die he's too smart and anticipated Kylo's actions. There's a fight between Rey and Kylo which ends up with Kylo revealing he's her cousin. Rey again beats him, but asks him to help her learn more about herself and they go to join the Resistance... The Knights of Ren show up and cause chaos on the planet and its Luke arriving that brings thing to a halt. He takes on the Knights allowing the others to escape and admits his failures to them (they're all his former students). Despite best efforts the Knights over power Luke, but before they kill him, they are called our away... but with a parting of 'just like your father, and you, your daughter will be mine'. The resistance retreats.
Rise of the Skywalker:
Not sure how I'd change yet - but there would be no 'Somehow Palpatine has returned line'. It would be definitely more complex and with clues throughout the first 2 films and perhaps the 1st 3rd of this film all leading to the reveal that he's alive... 'maybe a line abut how the dark side is the pathway to many abilities that people find unnatural
