The entire Disney Trilogy is screwed up thanks to TFA’s ANH-reboot and reset back to Empire vs. Rebels.
Lose the Starkiller base. New Republic is still in power. The First Order is a fringe secret organization in the outer rim, not The Empire again. They don’t have gigantic Dreadnaughts and Stealth Bomber ships.
The Last Jedi might have been a good movie on that smaller scale. (TFA would have been better as well.)
A single Star Destroyer and Rebel Transport locked in a lowspeed chase. That’s a potentially thrilling and dramatic set piece. U-Boat and Sink the Bismarck! vibes. (ALSO A CALLBACK TO THE OPENING OF A NEW HOPE).
As is, they required SO many universe-breaking gotchas to enable the main plot of the movie that the entire Leia/Po/Finn arcs were ruined. Rey/Kylo/Luke are the only things redeemable from this movie. Looking forward to The Last Edit.
