Dull action movie - completely misses what makes Star Wars great

Rating: 3/10 (17 December 2017)

I don't often write reviews here, but now that force has been awakened, and not by a good indicator.
I've loved Star Wars since kid years, 7 years old when the first Star Wars came out, and continued loving them even though Phantom Menace and Attack of the Clones weren't that good, and once, while working a mindless job for a whole summer, listened to approximately 100 SW audiobooks.
I loved The Forced Awakens, that rekindled the spirit of the originals, asking questions and wondering about the world, developing new characters, giving them surprising dimensions, and it was fun, so much fun. Rogue One was also a great success, even though it was much darker than other entries.
The Last Jedi reminds me on The Phantom Menace and Attack of the Clones, in that it's a technical marvel, with great music, but the rest is just poor.
Back is the silly creature humour comparable to dozens of Jar Jar Binks, lost is any sense of character development, lost is any sense of mystery.
All questions the fans asked after The Force Awakens get an answer, and it's pretty much always the same answer: "Who cares?"
There was a moment I enjoyed, which promised something new and fresh, but it fell quickly back into safe territory, and the promise of great potential just limped away.
The plot is surprisingly bad. The rebels are escaping the First Order, and since they can be tracked through light speed, they have six hours to get away to somewhere before running out of gas and being utterly destroyed. Subplots do nothing to further the plot, or deepen characters.
So, character development doesn't happen, the lively cast from The Force Awakens are turned into two dimensional cartoon characters. The plot is thin, and not worthy of the saga. There are layers upon layers of cool special effects and explosions, but that just doesn't work that well if the story hasn't been developed well enough.
I'm afraid that The Last Jedi has left me with the feeling of "Who cares?" and "So what?" - something that hasn't happened before, maybe it's just a sign of my own age, but maybe, and I suspect that's the case here, is that Disney and Lucasarts have made a huge miscalculation.
