The only reason that what Johnson did with TLJ - a script that was universally praised by pretty much all of Lucasfilm from Kathleen Kennedy on down - is divisive is that people refused to accept that the nearly 2 years of Johnson himself, Daisy Ridley, Pablo Hidalgo, and others systematically debunking or otherwise trying to downplay certain fan theories about where the Sequel Trilogy's story was going was legitimate.
TLJ is the only film in the Sequel Trilogy that was completely 100% problem-free, and it's because he not only understood the broader thematic tapestry of the SW franchise as a whole without having to have his hands held, but also offered a subversion of some of those thematic 'tropes' in a way that wasn't disruptive.
That’s...quite the statement.
I would argue he didn’t have a clue, and built the whole thing on subversions, few of which worked. Not least because if you subvert everything you can, it just looks like someone flicking switches for the hell of it. (Luke is a grumpy bastard! Luke throws away the sabre people were killing to get their hands on! The not-rebels-but-rebels didn’t get away safely! Luke dies! Snoke is wiped out with no explanation! Poe isn’t a hero! Nor is Finn — ok Finn has always been human Threepio — it’s not really any kind of galactic civil war because there’s a planet of rich people basically helping it along untouched by it! The hacker is a baddie, bet no one saw that coming! Reys parents are unimportant!)
Nothing is really subverted, because the film, for all its fun, almost exists in stasis...huge things happen, but nothing changes very much between its beginning and end. We start on the run, we end on the run, no one has found out much p, no one has developed much (apart from Finn to be fair..he’s fighting fairly voluntary to save others, and gets a kiss from a Rose. He’s seal.) there’s a change of management in the first order, but...well, kylo was already the big bad right? Oh...and it subverted my expectations by having Artois and Threepio, particularly, just there as set dressing. But TFA did that too.
Here’s a question...if Rey turns out to be Obi Wans kid, who hatched from a test tube where she was frozen on Jakku, or some other thing that links her back into the family Drama Star Wars always has been, Will it be getting something wrong or just subverting your expectations?
I mean TLJ subverted my expectations by not being as shite as it looked on paper or after the reactions to it. But I am not gonna pretend that Johnson came down from Mount Lucasfilm with Reys from his head.
