Ok, I've been meditating on how ROS could have been better and I came up with the following in the shower this morning. I think it addresses most of my issues with the movie in terms of characters and Pacing:
Act 1: Establish primary characters state of mind
Kylo Ren - hunts down the Sith homeworld and enters the temple. Finds clone of Snoke. Palatine is actually dead, but his machinations reach beyond the grave. Snoke comments on how Ren is focused, driven, clear, his inner conflict seemingly settled by the events of TLJ, and demands Ren bend the knee to his master. Ren refuses, battles, and handily defeats Snoke demonstrating that Ren is much more powerful in his current state. He destroys the temple, the clones, etc but before he leaves he senses something similar to what he has sensed when reaching into Rey's mind. He becomes obsessed with finding her and having her join him, their fates are intertwined. Ren meets with his knights aboard his flagship, thanks them for their quest to find the Sith homeworld while he was preoccupied during the events of TLJ, and gives them another quest to find and return Rey to him.
Rey- on the other hand is training. She's unfocused, unbalanced, she has her raw power but the events of TLJ have left her off kilter. She knows something is wrong, she feels the lure of the dark side, she remembers Luke's concern of her refusing to even resist it.
ACT 2: the Hunt for Rey and Civil War in the first order.
Hux leverages Ren's preoccupation with Rey and the Force to begin plotting a coup within the first order. Ren has delegated the operation of the FO to Hux, who brings over gernerals and troops to his side.
The Knights of Ren find the Resistance, try to isolate the heroes and Rey from support, and begin a battle. During the fight, any combination of heros are wounded, Chewie is mortally wounded fighting the knights. Rey, cornered and pressed, lashes out with the force, brutally defeating the knights but terrifying her allies and herself in the process. Ren appears through their mind bridge, surveys the carnage, then drops the bomb: her parents were nothing, but her grandfather was something: Emperor Palps. Rey fights Ren, but the tables are turned and he forces her to yield. Just as it seems the beaten down Rey is ready to accept her place and take Ren's hand Hux launches his coup against the FO loyalists, distracting Ren and allowing Rey to restreat.
Act 3: The final battle (gotta work, type this up soon).
Edit: K it's 1am and I'm drunk as shyte I'll try again tomorrow...
