Y'know TLJ has been out for over a year now and I've vented my anger towards it far and wide, but honestly, I'm just... still perplexed by Disney's decision making process?
I mean... maybe they approached it from the angle of a soft reboot, but we got a lot of visual redesigns that just felt out-of-universe. The Dreadnought, the new AT-ATs, a lot of the interiors to ships felt over-designed--like I get it, we have better technology now, but so many of the backgrounds (specifically during the Finn-Phasma fight) were just cluttered messes. It really bordered a "this doesn't feel like Star Wars any more" line.
Most of the best storylines of yore were not the ones that were carbon-copied or seen to their appropriate conclusions. Luke's influence was negligible to say the least, and Rey's whole time with him was a complete joke (where she LITERALLY discovered nothing about herself). The aggressively quick collapse of the New Republic was disappointing (especially considering all the politicking storytelling potential there). As many have said before, I think we were all willing to give TFA a free-pass on the originality as it felt like it was just drawing us back in to Star Wars. The decision to even SELECT Rian Johnson is... weird, imo. He doesn't really have a lot of experience with the kind of film that Star Wars is. Regardless, if TLJ was... just not a Star Wars film... IDK, I might be able to get excited about it, but at the end of the day it wasn't made in a creative vacuum, and Johnson not only obviously doesn't understand the Star Wars secret sauce, he was pretty explicit about not caring about even trying to make "A Star Wars film".
*Honorable mentions: Phasma going nowhere. Rey's parents going nowhere. Rose (Poor Kelly Marie Tran, she didn't deserve the hate). Han's descent into decided uncoolness. Snoke going nowhere. Et al. Poe suddenly becoming braindead. The regression of all prior character arcs in TLJ.
Honestly the best part of the new trilogy thus far has been the characters/acting--IMO, that's usually a bad sign in terms of quality. Despite TFA's generic-ness JJ actually did a pretty good job of setting up Rey, Finn, Poe, and Kylo--Johnson managed to butcher all but Kylo (who, despite initially being a flimsy character in TFA, ended up being the only saving grace of TLJ--weirdly along with Benicio Del Toro).
A general inconsistency in the feel of it all, small stuff like the space bombers and the hyperspace suicide--say what you want about shitty ole George Lucas, but never once in the original or prequel trilogy did you see something like that feel out of place.
[insert continued endless list of problems with the new movies]
TO BE FAIR,
It's not all bad. Kylo is great and Adam Driver is carrying the whole biz on his fucking BACK. Rogue One proved that there are still people out there who can make a movie that FEELS like Star Wars. Solo had a lot of good ideas, even if Ron Howard didn't bring his A game, and I can't blame him, the circumstances of his ascension to director made it difficult for him to really max out the film's potential. Despite TLJ's extreme awfulness (at least in the context of the series) Johnson is still a good director and gets some of the small moments right--Yoda, Luke's initial character (terrible development, backstory reveal, and conclusion though), Kylo just being a weirdo the whole movie lol. TFA gave us the best, in my opinion, lightsaber fight outside 2003 Clone Wars. Going forward, we've still got a pretty talented cast of actors.
BUT IN CONCLUSION,
Disney doesn't know what the hell they're doing. They saw an opportunity to pounce on some good IP, as is their modus operandi, but were not at all creatively prepared for it. They made the decision to "marvelize" Star Wars, but just didn't really understand the fan base. Obviously, it's also always the right decision to try and appeal to a new generation of fans (as Star Trek and other Sci-fi franchises have successfully done), but they did it in such a shallow and pandering way that pretty much blew up in their faces (in a lot of ways). Honestly, they are at least competent enough to hire GOOD directors, but they're so commercialized, so done-by-committee-d, that they just can't hire the RIGHT directors--even when the winning combos are right in front of them.
A lot of the problems, creatively, just kind of stem from modern American cinema in general--Star Wars is a surprisingly SLOW series--because even though it's a "Space Opera" it's really a "Roman Western" (that combines a lot of elements of almost spaghetti westerns and that trademark decline-of-society present in sword-and-sandal movies). That's not the direction our filmmaking is heading towards though, it's so aggressively quick that until Disney realizes that Star Wars only works when you get REALLY close up with the personal moments and REALLY far out with the epic battles and politicking and subterfuge stuff, it's just not going to work. That said, I doubt Disney is going to change their way of doing things/
