firstly; suddenly hyperspace travel is limited and so is impulse power, suddenly speed is a thing for literally no reason despite it being established that movement is almost irrelevant in star wars.
Secondly, remember that scene where Admiral Holdo sacrifices herself by blowing the rebel battlecruiser at hyperspace through the imperial supership?
If that’s possible, why don’t people just launch droid-piloted ships through hyperspace as a targeted nuke anywhere in the galaxy? And why can’t Kylo fire the giant door-busting gun from the remains of the First Order’s fleet from space, down to the planet.
It completely destroys my suspension of disbelief.
