But also, yeah Episode 8 is the worst movie in the main film series. It makes Episode 2 look good.
It also has weird "subversive" dialogue about sacrifice being bad that doesn't really fit what's happening in the movie itself where sacrifice of two characters saves the day. Which is "subversive" in the sense that a movie with dialogue saying "this is a shitty movie plot" is subversive.
It also rips off the ending of Return of the Jedi by killing the main bad guy so is "subversive" in that it trolls whoever was stuck making episode 9 without a functional villain.
There is a real problem with too many sequels and adaptations though.
Maybe 3rd. Jedi is gorgeous but the script for everything past Jabba’s Palace is a mess. Doesn’t know what to do with all its characters, feels the need to have them all around anyway.
As for sequels, we are at a weird time in history. Due maybe in part just how prevalent media is and how easy (relatively) it is to create, we've been super-saturated in "like X but with Y" stories. We have dedicated websites mapping tropes. It's hard to come up with anything that hasn't been done a few million times. AI will probably accelerate that, and I can't say I know what comes next.
WB under Discovery was already becoming an also ran and more financial engineering than a real company.
