The film since one of the first scenes hammers the fact that the resistance cannot win by doing big and flashy maneuvers that get their people killed to do something as small as destroying one enemy tool. The desire to be seen as a hero by destroying a dreadnaught or a first order canon ultimately doesn't matter when they have countless weapons aimed at your group anyway.
Instead sacrifice has to be made from a place of understanding that the goal may not ultimately be to destroy anyone or anything but to allow the rest of the group to live as seen with Holdo and Luke's sacrifices right before and right after Finn's attempt.Finn and Poe don't get this until the end. Rose is wise enough to know this and I feel it works for her. She is concerned about the resistance and is better at seeing the big picture.
This is correct. You have to key in on Finn saying that bit about "No! We can't let them win!" or whatever. His motivation for the attack was from a place of hate for the FO and not of love for his friends.
But here's the problem, Finn had just given a rousing morale boost about hope and buying time for help to arrive and you see Rose and everyone else gleefully nodding along in agreence. His head was in the right place. Then he hops in a speeder and it changes.
Its just a really awkward bit of storytelling and I'm not surprised so many people have issues with it.
The craziest part for me was that Finn and Rose escaped away to Canto Bight in that ship and nobody cared or noticed, including the First Order. They could have shipped off a lot of the Resistance via that method....
Yep, and Chewy casually drops Rey off and leaves no problem. It really undermines the impossible escape its trying to present.
