I 100% agree with Broom Kid’s excellent post above. The Last Jedi is at its core a movie about improvisation. It’s about preparing for the future and making the best choice at the right moment, and that type of message is very hard to nail thematically. I feel like that’s the reason many people, including me, were put off by the movie. It wants to convey a complicated message in the run time of an average blockbuster, and it results in some plot points and character arcs feeling unearned.
