Those are the issues I have. I can separate my distaste for the smaller aspects (why the fleet in the very first scene followed Poe in when he was told by a superior officer to back off, for example, or what the point of the entire sequence on the planet with the casino was.) from my curiosity at how the story ends.
My real problem is that I don't think they've set up character threads interesting enough to actually give a shit how it ends, now. It could end any fucking way you like, and because of that, it means whatever they do will probably feel pretty arbitrary. I'd argue that there were more plot threads that
needed to be resolved from ESB to ROJ, but they were more meaningful: Han needed to be rescued (not because of some arbitrary scenario, but because of a plot thread which started literally when Han was first introduced), so they could elaborate that whole thing as a huge set-piece adventure, which causes the movies to flow together, but also gives the audience breathing space to get ready for the main mission. the real meat here was that Luke x Vader x Emperor all had their own agendas in ESB, which needed to be resolved in ROJ. Luke wanted to defeat the emperor, and free his father, Vader wanted Luke to help him kill the emperor and rule the galaxy, while the emperor wanted luke to kill Vader and serve him in his place. Meanwhile, Han and Leia had a growing relationship, while Han was nervous that Luke and Leia would end up together. It's an intricate set of relationships that's worth having a whole movie to resolve it. Any equivalent in the current movies is only a shallow imitation of the set of relationships building up in ANH -> ESB -> ROJ.
Poe's a dead duck: went from happy-go-lucky ace pilot, messed up, now he's going to be triumphant hero dude in the finale. Who cares what shit Poe does next? He doesn't have any depth or elements to him.
Finn: had the most interesting backstory, completely squandered as he's running around just reacting to events and not really going anywhere. Shoe-horn in a fake love interest out of nowhere. Also, to be "inclusive" he's got an Asian girl now, but notice how they pair the minorities together, so that's actually a regressive step. For all the talk of "inclusion" this Star Wars is still pretty "white", and segregates off it's non-white characters together. And anyway, Finn has basically zero personality or quirks. His being a stormtrooper is
moot. Let's say he's the story equivalent of Han Solo from ANH. Han Solo's background
mattered to how he acted, and ultimately, to his big life-changing events. So far, Finn having been a stormtrooper hasn't really affected the plot
at all. You could change just a few scenes in the first movie, and exactly 1 line of dialogue in TLJ, and have him as a moisture farmer on Jakku who just happened to fall in with Rey.
Rey, while she could have been interesting, is basically a non-starter too. Nice that she has a "twilight-esque" entanglement with the
vampire villain. So more or less the only thing interesting going on, character-development-wise*, and it's basically the plot of something like Twilight or Vampire Diaries. I think the fact that
teenage girls have scored every Star Wars movie noticeably higher than any other demographic (since at least Return of the Jedi) isn't lost on these people. Kylo Ren being all 'emo' isn't any accident, and it's obvious why it's incongrous to the old-school vocal fans: it's basically injecting the teen vampire movie pathos into the franchise because
they have seen the demographic data better than we have.
* luke going crazy and sucking milk from alien cow nipples doesn't count as main-story character development: that's a cameo.
