Can't disagree with anything you said, and yeah maybe just a fresh start will be enough. Like you said you'll have people rage baiting either way so might as well get some new who.I get this, and i can relate to it in some ways.
I think that this Doctor, by design, was supposed to be a little different than the others. Because of how they split off, Ncuti's Doctor was supposed to be the fast track of getting past the hurdles that 14 and other Doctors had struggled with. The downside of that was that he was less emotionally stable (hence, the tears) and he had his own form of identity crisis.
Personally, I didn't mind that he could cry. But it did feel like he was always crying. It was one thing to show him as more emotionally available, but literally any rough moment would generate a tear. Mind you, they gave him some good moments, but that's still a lot to bear.
I think one more season, and Ncuti would have hit his sweet spot, probably with a new companion (or maybe just bring Ruby back). A new or different showrunner might have helped, too, because Russell was seriously smelling himself for most of this run. It's clear that RTD works best when he has someone to reign him in and focus his particular brand of crazy. On his own, he tends to have these big ideas that don't always make sense under scrutiny.
And I get the taking a break idea, but I'm honestly tired of the solution to a bad run being taking 5-10 years off. It might be my age talking, but I don't have the patience to wait out some imaginary cooldown period. It's not like the fans will be less toxic the next go round, anyway.
Just get Russell the fuck away, he was once great and saved the show. That time is definitely gone.
