Well, I finally found the review that most matches my feelings; abusive use of exposition, not feeling anything for anyone, Carrie Fisher performance being exploited and even used the same word I did when explaining the plot - cockamamie.

The wit, wisdom, charm, and imagination of Star Wars is gone. Take, for instance, Rey’s training. It’s as if J.J. Abrams watched a wizened Yoda guiding Luke with lessons about transcending mind and body, yet thought the obstacle course was the point. You almost want Beat Takeshi to show up with running commentary to liven up the whole affair. Even an implied Han and Leia dynamic, attempted between the ex-smuggler Poe Dameron (Oscar Isaac) and Zorii Bliss (Keri Russell)—a female bounty hunter costumed in such an Art Deco throwback we might as well call her Daft Punkette, the Racketeer, or C3P2—gets thrown into the narrative cacophony, just to “no ” the Poe/Finn relationship resonating within the fandom’s diversity. Like Disney blithely dispatching 42 years of canon, even C3PO doesn’t hesitate to erase these horrid episodes from his own memory. After all, how much do you want to bet there’s a backup drive?
Then there’s the unused footage of Carrie Fisher that seems patched in, like it was shot for a completely different exchange but repurposed here. There’s something gauche about robbing an actor of her agency, the clarity and purpose of her performance. Here, they re-animate Fisher, only to have to justify her death in service to a male character’s arc in a way that, the explanation itself feels like it’s capitalizing on something to which we shouldn’t be a party. It feels cheap, like the moment in BOWFINGER where the director, Bobby (Steve Martin), tells his ingenue, Daisy (Heather Graham), he’ll never abuse her trust, while pilfering her credit card from her purse.
What was once a thoughtful, evocative series, taking us to distinct worlds of sand, ice, lush vegetation, is now a galaxy surfeit with desert planets and earth tone linens, infantilized cultures—a sort of National Geographic survey of “savages” from exoplanets that just happen to all dress the same.
