Why not have Kylo turn into a badass Supreme Leader and show that for most of the movie? Show what he's capable of when being conflicted isn't slowing him down. He could've beaten Rey at the same point in the movie, but just have her rescued by her friends. That would allow the best actor in the entire cast to have more than one word of dialogue in the entire second half.
Well everything in bold actually did happen so I guess I'm not seeing the issue. Supreme Leader Kylo owned every scene he was in (even stood his ground against Palpatine!), the entire FO High Command feared him (even secretly-answering-only-to-Palpatine General Pryde dared not oppose him) and he was in command of every encounter with Rey until Leia saved her.
On a side note one thing that was cool about him charging her with his TIE Fighter on Pasaana is that when she's running and they cut to the interior of his cockpit you actually hear that super high pitched beeping noise from Vader's ANH cockpit that would go off whenever he locked on an X-Wing. So Kylo even went so far as locking on to her physical person and could have blasted her with all four quad cannons if he were so inclined.
As for his dialogue on Exegol what do you mean he nailed that "ow" lol.
I would've preferred that. You guys wouldn't, but I wish you could explain to me why. No biggie, though, gentleman; just different preferences I suppose.
Yes most definitely and obviously with you wanting such heavy callbacks to Hayden Christensen and the prophecies of the PT there was just never gonna be a scenario where we were both happy I guess, lol.
