Yet the film has all the Skywalkers killed off and the descendant of Space Hitler™ (whose return ruins the meaning of Anakin’s sacrifice, by the way) taking on the surname of Skywalker at the end. Also, General Hux is redeemed (which ruins his entire character even more), Anakin’s lightsaber and Kylo’s helmet are fixed (which ruins the meanings of their destructions in The Last Jedi), there’s the “fake-out death” cliché, there’s a character who only exists just for a reveal that she is Lando’s long-lost daughter, etc.
Well, Leia dying is probably going to be the biggest missed opportunity of this film, but I don’t know how that’s a valid criticism considering real life events.
Perhaps once Carrie Fisher passed, the powers-that-be should’ve just, y’know, re-edited TLJ so that Leia was the one who died and Luke survived.
Their options were either to rewrite and reshoot half of The Last Jedi which was almost in the can at that point or to rewrite Ep. IX which was still in pre-production. Practically, financially and artistically I’d say they made the right call.
