> Particularly divisive was the reveal that Rey's parents are insignificant; many fans had expected her to be Luke's daughter or to share a lineage with another character from the original trilogy.
Rian Johnson: "It's something that is absolutely going to be addressed... The other part of it is there are lots of surprises in this movie and lots of twists and turns, and I really want people to experience those when they see the movie for the first time. "
Ok, so years of oh, ah, and then the big lineage reveal comes and she's just a peasant girl. Screen rant called this "anticlimatic," which is was. The easily could have managed that earlier with a decent plot and decent writing, but the whole trilogy seemed to be written by a bunch of high school students.
Most of the other issues are from TFA, because that movie made no sense. Oftentime strategically, movies do not make any sense, but that does not hamper their plot (in the movies Lord of the ring The Two Towers/The Return of the King, strategically the decisions are pure nonsense; when the books did a lot of work to explain how they end up in those very bad positions, but hte movies are still great if you don't really think about it). In TFA, i just can't understand why the republic are now rebels who use guerrilla/freedom fighter tactics. I don't understand the strategy behind anything, and honestly, the plot devices are too big to be excused. At least TLJ tries to answer the " but why?", often poorly, but at least you have explanations (and sometimes some punts to JJ abrahams, but honestly, fair play.)
I'm reminded of the related Mr. Miyagi meme, LaRusso: "Will you train me?", Miyagi: "I hate everything and want to die." The End.
That said, I've never been a big Star Wars fan and not super invested either way.
