Alright, so let's do some counting.
First off, there's 400 people on the ship, not thousands or even a thousand. From Holdo herself:
There are four hundred of us...
on three ships.
We're the very last of the Resistance
We also know that there are many injured from the preceding battles who are part of the headcount but obviously can't do anything.
Poe, Rose, Finn, and the bridge controller are part of the mutiny. That is augmented by members of Poe's fighter squadron, which we can just assume to be 10 as you had proposed.
Now we also know there have been at least 3 deserters. From Rose:
You know...
Just this morning, I had to stun...
three people who were trying to jump ship.
In this escape pod.
I would say it's fair to assume that deserters are not going to be just granted the freedom to try to desert again. It's likely this number is even higher given the way Rose phrased that statement.
Counting up the deserters and mutineers, that's at least 17 people who are clearly suffering from morale issues. That's a little over 4% of the remaining survivors, likely coming up to 6% if we discount the injured and incapacitated and grant that were probably a couple more deserters.
Given the objective of the mutiny was to seize control of the bridge, it wouldn't make sense to make it a widespread mutiny.
You keep bringing up the point about the 30 seconds before the mutiny started. I'm not arguing that was when she failed. Holdo failed several hours before when she had the time to reassure the remaining survivors after Leia was incapacitated.
You keep mentioning Adama and I don't particularly want to get into a comparison because those things always get sidetracked. But he's massively flawed as a leader. That was absolutely the intention of the show. I honestly don't think you're being at all fair. You're waving away complaints about Adama but using them to fuel your argument for Holdo.
If Holdo had a line where she said something along the lines of, "I should have kept a tougher lease on Poe" instead of that silly "He's a troublemaker. I like him" line, I probably also would have been more favorable towards Holdo. Admitting fault is another characteristic that for me anyways defines good leadership.
And I keep bringing up Adama because whenever I watch BSG, it feels believable compared to when I watch pretty much anything Star Wars. Adama as a character sold me on the idea that he's a good leader, whereas Holdo just doesn't unless I'm willing to abstract away a lot of things and just roll with what the film wants me to think.
But I digress at this point. You and I both know the intent of the subplot was for Poe to learn his lesson. We simply have different thresholds for what we consider good leadership, which in itself ultimately just boils down to how well the details were presented to produce the intended narrative because it's pretty clear that Holdo was intended to be right all along. It just doesn't feel that way for me, which is why I'm so peeved about it.
I consider the narrative subtle when the intent isn't thrown directly at me from the get-go. At the very start of the film, Poe disobeys a direct order from Leia. At that point, it's pretty much established that there is going to be a subplot about Poe learning to be more cooperative and less impulsive. Part of the problem might be that it's handled so bluntly, or the fact that Poe is just so unlikable to begin with. I'm actually curious. Who here actually likes Poe as a character? Agreeing with Poe's decision doesn't mean you have to like him either.
I can never tell whether people who don't like Kylo Ren either don't understand what his purpose as a character is or don't understand why he is the way he is, because it's always one or the other.
Why does it have to be either one of these circumstances? It's not like they're hiding the notion that Ren is struggling with the dark side, or that he had a ****ty childhood.
I sympathize with Ren to a degree, but I don't condone his actions. The bigger issue is that I feel like I'm watching this:
https://www.youtube.com/watch?v=FaOSCASqLsEI am 99% certain that I'm not supposed to be laughing at Ren outside of the SNL skit. You can write a character that's struggling with a crisis, even one that's sympathetic, but it doesn't mean the audience has to like them. And really that's the issue I had the film. I mentioned this way back earlier on this thread that the pacing was all over the place. The only time I actually feel sympathetic to Kylo Ren is when I abstract him away from the film, which is also the same way I feel about Anakin. Conceptually, they are characters I should be caring about, but when I watch the movies, I don't feel it. And that's the problem.
So to be specific, I like Kylo Ren conceptually, but I dislike Kylo Ren when I see him in the film. Maybe I'd like TLJ more if I was reading it as a novel.
