I keep thinking now during the Rey/Kylo vs. Praetorians fight, I sort of wish that when the one guard snaps his staff in two and starts swinging them moving towards Rey, that she would pull out her blaster and shoot him, Indiana Jones style.
I would have bounced off the ceiling at this.
The Holdo sacrifice scene is one of the best moments in SW. I think we're picturing Ackbar or Lando or someone else in that spot because we wanted it to mean more, to us and because the story so far hasn't served those characters. I think Wedge also would have been a great choice in this role, but not sure where Denis Lawson is anymore on SW and that wasn't Rian Johnson's interest.
He wanted to tell a story that sidelined Leia in favor of giving Poe an arc about learning leadership skills. The movie wasn't big enough to explore all the possibilities in the arc - is Holdo good? Bad? Neutral? Poe's reckless behavior both with the bombers, participating in the Canto Bight diversion and the mutiny all contribute to getting A LOT of people killed. Sure, he learns something (listen to your leaders) but at what cost? And what weight does he carry, knowing that cost? We don't see it.
