You say this like writing classes don't exist which teach how to properly tell and structure stories.
Then I'll hop in, as someone who majored in film and media lol.
Luke goes from going into hiding leaving a map behind so he can be found if he's ever needed again to suddenly leaving to die and not wanting to be found.
This one definitely isn't quite clear, but two things: Lucas's intention was to have Luke exile himself. Also, TFA definitely uses "map to Skywalker" a lot, but Han also explicitly states that they
think Luke went to the first Jedi temple. It's poor wording for sure, but Luke didn't leave the map behind himself.
Luke who thought Darth Vader, child murderer, could be redeemed, figured the best way to handle a teenager having dark thoughts was to maybe kill them in their sleep.
It's explicitly stated that there was no thinking involved there. It was a momentary "holy shit that's a lot of darkness, panic now," immediately followed by "uh no this is Ben." Kylo Ren woke up at exactly the wrong time. This is basic comprehension. Luke's quote:
I saw darkness. I sensed it building in him. I'd seen it in moments during his training. But then I looked inside, and it was beyond what I ever imagined. Snoke had already turned his heart. He would bring destruction, pain, death, and the end of everything I love because of what he will become. And for the briefest moment of pure instinct, I thought I could stop it. It passed like a fleeting shadow. And I was left with shame and with consequence. And the last thing I saw were the eyes of a frightened boy whose Master had failed him.
Bolding mine.
Kylo Ren's scar moves so it can look cooler.
Yep. I don't personally have a problem with that, though; even the original trilogy is full of inconsistencies. After all, Han's outfit changes from shot to shot just before he's frozen in carbonite, and Leia's outfits swap around when it's revealed that Lando betrayed them, as a few examples.
Luke's lightsaber from Cloud City is completely forgotten about.
The one he drops? That's the saber that Rey uses throughout TFA and TLJ, so I'm not sure what the issue is here.
The film takes place right where Force Awakens ends yet acts as if there's a time skip with injured characters who were mortally wounded being back to 100% within the hour.
The movie explicitly shows Finn being treated with a strange liquid, which I've always assumed was bacta, just like what healed Luke from frostbite pretty quickly.
Despite taking place over the course of 18 hours there's more travel between worlds than any of the prior films making distance completely irrelevant when before it mattered.
We don't get any sense of distance (for better or worse) for the other planets, but what do you mean when you say distance was relevant before? Luke manages to go between Dagobah and Cloud City very shortly after he realizes Han and Leia are in danger, and we explicitly see the passing of time as Finn and Rose have their excursion on the casino planet. The timeline of TLJ is a bit funky, to be fair!
Look the film was shot beautifully, the score was amazing, people did the best they could with the material at hand but objectively the story is bad, poorly written, thought out, and doesn't work as a sequel to another story. It drops plot threads it's no longer interested in following, picks up new ones with zero explanation, and is very clearly doing its own thing despite being the second act of a three act bigger picture.
This isn't a matter of "is it art" it's just bad storytelling and that's a very objective thing.
I'm glad you can talk about some positives with it; I appreciate that. However, it's not
objectively bad. We demonstrably see character growth for Finn, Rey, Poe, Rose, and Kylo; the plot is moved forward by Kylo taking over the First Order and Rey taking the Jedi texts; the themes of the Force being in everything are furthered through the sequences on Canto Bight. There are flaws in it (Canto Bight could have been tightened up; the reason Finn and Rose were arrested was flimsy AF; etc.), but that doesn't mean that the story is objectively poor. The movie has a demonstrable beginning, middle, and end; you can literally map it out on a basic plot structure outline. What plot threads from TFA were dropped?
On-topic, probably Sword and Shield. A long-running franchise beloved by many whose newest iteration has people on both sides refusing to listen to any criticism, but also has one side blatantly ignoring things that were said.
