The more I think about this movie the more disappointed it makes me. It has soured my opinion on the trilogy as a whole (which I absolutely loved until now), and maybe the 9 films.
While I don't think it's a super retcon of TLJ like some reviews say (in fact, I was surprised in how faithful it was in some details and following some plots), it also completely misses the point of that film and the best decisions it made (of course, everything related to Rey's family, the lack of a real Resistance, the whole idea of the light and dark side being just an old interpretation of the force, etc). I find baffling that the part I liked the most is a copy of one of the best moments of TLJ, but worse (when Ghost Luke and Rey talk, I think TLJ did it WAY BETTER with Luke and Ghost Yoda, way more meaning).
This third film should have been Rey vs Kylo, period. I'm still not sure why Palpatine is in this movie, other than "we need a villain!", yet again, Kylo should have been that. You don't have to kill him, redeem him at the end if you want to, use the Knights of Ren for that (which are fucking useless by the way, after being eternally hyped after TFA). And, at worse, if you're going to make Rey a Palpatine and build a movie around her insecurity about her family, at least make it a real plot, not as a superficial theme to drive people to other Macguffins.
Honestly, I liked the second half of the movie more, because the first half is a disaster, it's a movie without any direction or plot, just things happening. And, I have to say, except for the kiss, I liked the ending in general.
Though I'm baffled that no one at Disney (or JJ) saw the finished movie and even thought how the ending is AN EXACT COPY of Avengers Endgame, with the same exact beats (Cap with Mjonir/Ben with Anakin's lightsaber, Falcon on the radio + Portals/Lando on the radio + hyperlight ships, "I am inevitable and I am Iron Man"/"I am all the sith and I am all the jedi"......)
It's not the worst, it has its moments, but it definitely lets down as a trilogy finisher, a saga finisher and as a movie in general.
