When did force users become so ridiculous, so godly. Even little things like Luke lifting the X-Wing out of the ocean annoy me. Force ghosts were never able to interact like that with the real world, and if they could it would change the battles entirely. Luke would have confronted Palpatine with Obi-Wan and Yoda and probably even Qui Gon Jinn, Mace Windu and the whole rest of the Jedi counsel as ghosts. It's stupid. It makes Jedi unbeatable, removing any stakes. What makes it only more annoying is that Rey could have lifted the X-Wing out of the ocean herself. Disney repeatedly completely screws logic just for dramatic effect.
I actually blame The Force Awakens for most of the problems in The Last Jedi and the trilogy as a whole. It's Rian Johnson who tried to salvage Abrams' mess. Abrams and Disney didn't even TRY to imagine what the galaxy might really be like after the deaths of Palpatine and Vader. There was no world building. The Empire wouldn't have just turned to "ashes," as the opening crawl in The Force Awakens stated. There still would have been much to do for the Rebels. I would have imagined Leia as representative of the peace keepers trying to help govern a new Republic or expanded Alliance. Perhaps Commander/General Solo with forces of the new Republic/Alliance would have tried to mop up the remaining Empire. Think about that scene at the end of Rise of Skywalker when the huge allied space fleet shows up to save the day. That should have been the allies from the start of Episode VII. I actually would have started the new trilogy with the Empire on the losing side, from the perspective of Storm Trooper Finn or maybe an Imperial Rey. The first movie would have been about the Empire's resurgence or the First Order rising from the shambles (not the ashes) of the Empire, under the leadership of a new force user, whom I haven't decided should be Sith or not. Or, perhaps even better, a band of force users, a few who left Luke's school. They would have been unique characters who actually interact, wearing no masks (so as to give them more character), with Kylo Ren or whoever sort of but not quite at the top. They would have been more of a threat to Rey, the Knights of Ren that are briefly mentioned in The Force Awakens. That would have been SOMETHING DIFFERENT.
I wouldn't have wasted the last thirty years of Luke's life either. If I did make him a McGuffin, someone the Empire and Alliance are searching for, I would have, at the end, when Rey finds him, shown him not by himself on a little island, but with a school of apprentices he has been teaching in secret. The Force Awakens pissed on Luke before Johnson ever did. The trilogy could have also been about Luke and his apprentice, perhaps Leia's son or daughter, and how he tries to train him/her with the dark shadow of his family hanging over them. We would have witnessed that instead of being told of the events by characters. I would have actually had him survive the trilogy. Why did the whole trio have to be killed? What's wrong with just dying of old age after a meaningful life? The space fantasy could end "happily ever after." You just know Rey and Finn will be murdered in their fifties/sixties too. Han I see as necessary, since Ford wanted out.
Abrams, under the poor direction of Disney to do a soft reboot, just kept everything the same. Another desert protagonist. Rebels against a huge Empire again, barely mentioning the Republic or explaining anything that happened in the last thirty years. Another planet-destroying sphere. Solo still smuggling. The Jedi still just Luke, another hermit. Leia still with the underdog Rebels. Rey another child of a Sith. A Sith lord manipulating the antagonist again. It was all so lazy, safe, regurgitated and unrealistic, demonstrating Abrams barely thought the whole thing through. They wrote Episode VII and started filming in almost no time at all. I can see why Johnson wanted to cancel his mistake. They should have taken another year, at least, writing the three movies beforehand.
I hope they learned a lesson with this trilogy, to take their time writing it. Just because you paid 4 billion dollars for the franchise doesn't mean you have to start pre-production like the next season. George Lucas had been cooking the idea for the The Star Wars series in his head for years before he ever filmed the original. Some things obviously changed as they made the films, but it definitely helped having a plan. Next time, the writers should formulate a three part story covering the whole trilogy and then have the producer make sure the directors follow that vision. It's okay if they take a long while to write it. I know one of the reasons Avatar 2 is taking so long is because James Cameron wrote out the whole rest of the series before he began filming the sequels, and I'm sure that will pay off in the end. At least the original trilogy is a completely self-contained story and isn't hurt by Disney's failings and poor handling of the original characters. Looking back on how badly they screwed up, even the prequel trilogy is starting to look better. I can see myself rewatching those, but I have no desire to ever revisit this mess. I liked some of the things from the sequels, but there are so many major flaws, and it's hurt way more by having a crappy end than the prequels were hurt by having a crappy middle.
Another thing that bothers me are the fans, who try to explain away all the lack of world building with side stories like the books and TV shows, which most people aren't gonna read. That's not how film stories are told. You can't take out the first thirty minutes of Die Hard and expect people to read a book about how John McClane goes to Los Angeles and terrorists (or robbers) hijack the tower. Nobody would be okay with that. If a film or collection of films can't explain itself and has to rely on other media, it fails as a story.
