Thoughts on the season overall??
IMHO the core flaw with the season, beyond all the execution, is how they botched Michael's arc.
Go back to Episode 1, and Michael pretty clearly has a lot of flaws from the getgo. She's not a Mary Sue, despite what the trolls said. He flaws seem to mostly boil down to unresolved negative feelings around the Klingons, then (somehow) being raised by Sarek and learning she should suppress her emotions rather than face them.
But did those flaws lead to a mistake? No, they didn't. Michael kills the Torchbearer, but it's by accident, more or less, and T'Kuvma's dialogue makes it clear it wasn't really a big deal. Michael's "mutiny" (which isn't really a mutiny, because you need two or more conspiring) was a failure - she never fired on the Klingons. Furthermore the cutbacks to the Klingons seem to make it clear that Michael's course of action
would have been right. The "mutiny" killed her career, but in the macro sense, she had the right response to the problem, despite her flaws. The only mistake she makes is choosing to kill T'Kuvma after Georgiou gets shanked, but frankly no one other than her knows about this (Saru knew the plan was to capture T'Kuvma, but wasn't there to see what happened. Yet somehow the entire war gets blamed on her.
What this suggests to me is that an early draft of the first two episodes had the Klingon War being
actively her fault. She was supposed to fire on the Ship of the Dead, and actually make a big mistake which set off the war. But somewhere along the way, either the showrunners who took over for Fuller or CBS got scared about a lead that flawed, and they choked. Sort of similar to how Paramount had this maxim during the Berman Trek days that the captain always had to be "right" which fucked up Voyager (neutering Chakotay since he could never win an argument with Janeway as XO) and Enterprise (where
Dear Doctor was made far worse because the studio wouldn't let Plox disobey Archer and do a genocide on his own, so instead Archer had to extol the "wisdom" of it himself).
From episodes 3 to 9, I thought Michael had a great character arc. We slowly see her come out of her shell, losing layers of Vulcan repression and embrace her humanity. We see her relationships with the rest of the cast slowly transform from distrust to grudging admiration to outright friendship. Returning to the Ship of the Dead, facing down Kol, winning back Georgiou's badge...all of that was great symbolically.
And then Chapter 2 happened, and they just tortured her for no good reason. Her boyfriend was unveiled as a Klingon sleeper agent who tried to strangle her to death. Her captain was unveiled as a mustache-twirling villain who was just trying to get into her pants all along. And someone with the face of her dead surrogate mother is now lady Hitler. What does this tell us about her character? Absolutely nothing. What lessons does this teach her? Beats me. How does she grow through this arc? She doesn't, she just endures.
Then we have the final stretch, when she decides, randomly, to just trust MU Georgiou. Her spidey-sense ends up right here. But the issue is this isn't growth, this is what she's always been like. Michael from the first episode has been someone who makes rash emotional decisions and then covers them up after-the-fact with layers of Vulcan denial. The decision to trust MU Georgiou is built upon nothing other than her looking like PU Georgiou, and the fact that she trusted PU Georgiou. It works, because the plot needs it to work, but her decision in the 11th hour isn't built on learning lessons from any bad decisions that she made earlier.
