Does this result in anything bad actually happening?
How about a more mournful ending as a lot of good people had just died, and the first order basically stands unopposed in their rule.
Holdo expected everyone to trust her on blind faith.
Hux was definitely inconsistent with his previous appearance. He went from being a feared military leader to nothing more than a comedic gag.
Even the whole plot about Poe trying to grow out of the reckless pilot persona was half baked. Heck, when the mutiny happened, I thought that was Poe trying to enter into a leadership role. Heck, the fact that the mutiny went on for so long shows that many members of the resistance see Poe as a better leader than Holdo.
