Good sci-fi action movie, but it's simplified Star Wars

Rating: 7/10 (14 December 2017)

Overall I enjoyed 'The Last Jedi', great spacebattles, fx, nice jokes and several unexpected plot-twists that made the movie an enjoyable ride,
I'd definately watch it again, but I am unsure how to rate it against the other Star Wars movies. It's better than TFA and the first two prequels, but other than that I'm not sure.
There were several things I found unsatisfying:

All strong characters happen to be women. All male characters have some obvious weaknesses/flaws. Although I don't mind strong female characters, this movie went to an extreme.
Most new characters of the new trilogy are just underdeveloped., but particularly 'Poe' is awful. He doesn't seem to be one bit distraught after having lost so many friends in battle (mostly due to his own desire to blow things up).
Snoke appears to be extremely powerfull, but who is he? And he is killed off really easy, making him in one of the most unsatisfying villains of all time.
The New Republic is gone and The First Order is the dominating power, yet is pre-occupied with a handfull of rebels (1 cruiser + some support ships). The size of the Resistance is just pathetic. In the original Trilogy it was already difficult to comprehend why the Empire is so concerned about a handfull or rebels, but this is just ridiculous.
Captain Phasma survived the destruction of starkiller base, only to be killed off in a stand-off by Finn, just like the badass riot-Trooper in TFA. Very unsatisfying.
The whole casino-world sub-plot was unnecessary if the admiral just told Poe about her plans
Carrie Fisher's death was a shock to all of us and I imagine they wanted to give her lots of screen time, but storywise they have created a crux as there were two great moments to end Leia's character arc in a satisfying way. She miraculously survived the first attempt and at the 2nd moment, she should have been the one to stay behind on the cruiser. They already said that Leia won't appear in SW IX, so apparently they'll kill of Leia off-screen, which would be abysmal.
Kylo Ren said that Rey's parents were unimportant people. I assume he was lying, otherwise Rey's existence is just as unsatisfying as Snoke's.

Things I particularly liked:

Kylo Ren's character development. Snoke said exactly what everyone thought about his character and it was nice to see him making his own choices instead of being a puppet.
I became a bit annoyed by a growing desire of fans that 'Neutral-alignment' would be the best alignment, instead of Sith/Jedi. I'm glad Disney didn't yield to this lackluster nonsense, but kept the Jedi as the main protagonists (Rey's took the sacred Jedi Tomes with her).
cool plot-surprises.

If it wasn't a Star Wars movie, I'd say it was a good Sci-Fi action flick, but being Star Wars, I found it lacking: the main downside of this movie is that it does not feel like an adventure that Star Wars is supposed to be (like the original trilogy & prequels). It's more like a small part of such an adventure streched out to fill 150 minutes.
It's basically a simplified Star Wars and lacks the world-building scope that George Lucas created with his two Trilogies.
