This post contains significant spoilers for The Last Jedi. Seriously, I don't think there's anything that I do not spoil.
When the DVDs for The Last Jedi come out, someone will immediately make an abridged version where pretty much every scene of Finn's is cut. And that version will be superior to the theater version.
That's actually a little unfair. Finn's story line wasn't bad, it was just pointless, and not as interesting as the other story line.
I went into The Last Jedi with low expectations, due to the negative buzz around the movie. The Last Jedi was better than those low expectations. It's not a great movie, but it's not as bad a lot of people are making it out to be.
Though it started very badly. I don't expect scintillating wit from Star Wars, but surely we can do better than a Bart Simpson prank phone call and a "Yo mamma" insult.
Let's start with the good. The Rey/Kylo Ren/Luke story is quite good. I liked Rey a lot more in this movie. She's restricted to being a Jedi, and that narrowing of her character makes her stronger. I liked that they didn't give her an "aristocratic" background. I rather liked the way they did the connection between Rey and Ren with the split scenes. Mark Hamill was really good as Luke.
There's really only three criticisms I have about that story. First, I think Luke's jump to wanting to end the Jedi was a bit of a stretch. Perhaps they could have gone more classical, and have Luke Foresee what Ben Solo would become, so Luke tries to strike him down, and in doing so makes the prophecy come true. That would give Luke a better reason to blame the Force, blame his teachings.
Second, because the writers didn't have an ear for resonance, they actually end up validating Kylo Ren's killing of Han Solo. Kylo Ren keeps saying that one must "murder the past, and free yourself." And what does Yoda do? He "murders" the past of the Jedi, and frees Luke and Rey from it. There is a totally unintentional parallel there.
Third, killing Luke was kind of pointless in the way they did it. Why go through all the trouble of having a hologram there? If you were going to kill Luke, it would be better to have Kylo Ren strike him down, echoing Vader and Ben Kenobi. It kind of feels like they decided to kill Luke after the fact.
In any case, that's the good story. Then we come to the other story.
I think this story underwent a substantial rewrite. I really think that the initial script started with a "traitor" subplot that was later cut and replaced with the casino planet. Someone on the fleet would be a traitor with a tracking beacon that allowed the First Order to track the Rebel fleet. Shades of A New Hope, where the Empire planted a beacon on the Falcon, tracking it to Yavin.
This would make Admiral Holdo's secrecy far more understandable and correct for the type of character they were portraying. It makes the first scene where they declare tracking through hyperspace to be technically impossible much more sensible. Immediately following it with a scene where tracking through hyperspace was declared to be technically possible was really dissonant.
In any case, this infiltrate-the-enemy story wasn't really good, but it wasn't that bad either. Kind of meh. Though it did seem kind of weird to be more concerned about the cat-horses than the child slaves tending them.
I did like that the moral equivalence guy sold them out. Made a strong (probably unintentional) statement about moral equivalence.
I also really liked the scene where General Hux was going to shoot Kylo Ren while Ren was unconscious. That was the one truly elegant scene in the movie.
So that's my thoughts on The Last Jedi. One good story balanced against one mediocre story. Good performances by Daisy Ridley, Adam Driver, and Mark Hamill. Lots of small dissonant moments that don't really "mesh" with each other, but the overall arcs are okay. Probably due to a lot of "scriptwriting-by-committee", I imagine.
I do wish that the writers had been truly bold, though. Imagine this movie, but where--after killing Snoak--in the scene where Kylo Ren offers his hand to Rey, she takes it, and spares the lives of the Rebellion and her friends. That would have been a crazy setup for the next movie.
