The Resistance or w/e they are called were literally just flying around the Sith planet not firing at any of the planet killing lasers, just getting absolutely slaughtered, until the armada of cargo ships shows up, at which point they go "Oh that's right, we had a plan to blow up the lasers to destroy the ships" and they blow up the entire fleet. Then after all the ships are destroyed, they just wipe their fucking hands and go "Good job guys" and immediately leave instead of doing search and rescue for all of the people that got shot down and executing every single last fucking sith follower on the planet. That movie makes me want to pull my hair out. The space battle in TLJ was bad enough.
