In any case, I thought of something significant. While Leia demotes Poe for wasting their resources in destroying the dreadnought after they jump to hyperspace, in the end, his actions proved to be something that kept them from total destruction because that dreadnought’s weapons could probably have destroyed the fleet through their shields. So Poe saved the day at the beginning of the story and Rose’s sister did not die in vain and at the end of the day, Luke and Rey save the last survivors to fight another day. So the movie is not as dark as it could have been. But even so, Poe learns a valuable lesson about command and when to take risks and that it needs to be more calculated and less reckless.
