Look, The Last Jedi is just *bad*, and I'm not even talking about the storyline with plot holes big enough to fly a frozen space Leia through.
Star Wars was always visually exciting and detailed. That background is what made the galaxy far, far away feel like a real place, a big setting with characters, places, and events worth exploring. TLJ lost that. Here's some examples:
In RotJ, the throne room battle scene had consoles, stairs, alcoves, and windows with a view of space outside, all seen during the battle. TLJ's scene had a red curtain.
In ESB, the Hoth battle was explained with the shield generator and the Imperials marched in through the wastelands with blowing snow as Rebels defended from multiple lines of defenses and trenches while Rogue Squadron engaged the AT-AT's. You had Admiral Ozzel, General Rieekan, poor Dak, and dozens of troopers on both sides shiwing an epic struggle. In TLJ on Krait you had 7 speeders stop and turn around against a straight line of FO forces and one unnamed trooper say "salt".
Even TLJ's only marginally detailed scene, the useless side quest to Canto Bight, paled in comparison to Maz Kanata's watering hole in TFA.
And let's talk the score. John Williams is a master and every SW film he's worked on has had a memorable piece until now. You don't notice the score at all.
Continuing on, all of the other films (yes, even including TFA) have had quality cuts in between scenes. TLJ just flashed to the next scene like a sitcom.
Don't even get me started on the story, with the hyperspace jump stolen from Lilo & Stitch, the chase scene from Fast & Furious 6, or the flagship monologues from Space Balls.
I've decided that Rian has screwed up too bad and gone back to the EU. I'll take the yuuzan vong, 17 clone emperors, and planets full of force witches over this drivel.
