tl;dr: 4/5, the public is Wrong about everything, #DeconstructGeorgeLucas
I did not believe in this movie, not even remotely. After the unnecessary everything about the prequels and the Mouse Council plastic playride of The Force Awakens, I was fully convinced that the sequel trilogy would be nothing but Extruded Culture Product which entire departments of marketing executives had approved every single syllable of. I thought it would be Empire Strikes Back's skinned corpse being worn by a sexually aggressive zombie of Walt Disney set to all top 20 Christmas songs played simultaneously, wailing the wail of the damned as the children stare into their Star Wars action figures and try not to cry even though mommy and daddy are drunk and exchanging death threats with the neighbors again. But I was wrong. Somehow, somehow against all possible odds and the Ghost of Capitalist Future, this movie managed to be its own creation, and an immensely necessary one for Star Wars.
I don't love this movie to death or anything (see my rating), but it sure as shit is the best piece of Star Wars media in over a decade. It's surreal to me looking at the non-critic reviews or the other posts in this thread. I guess The Last Jedi was just made for me. See, my background here is one of Star Wars heresy (and really, if you're gonna have an overzealous fandom in your life, you could do better than George Lucas' failure of a Buddhist Fantasy Romance), because my favorite piece of Star Wars storytelling is not any of the films. It's the two (and there are only two) Knights of the Old Republic games, which I loved above all else because the central thesis of their storylines is the deconstruction of Star Wars. KOTOR I does this by making the Jedi and the Republic kinda evil bastards, KOTOR II goes even further by making the greatest enemy the Force itself, as an omnipotent oppressor who cannot be overthrown.
This brings us to The Last Jedi. It has its faults, mostly in the beginning and a few stupid things like the bad CGI on Space Leia and the whole Yoda scene, and the continuous risk of having two climaxes instead of one (though some women like that, I've heard), but what it gives is so much more, because it is an honest to god deconstruction story in the main movies themselves. I thought it would never happen. I saw some hints back in TFA's marketing, but I figured from the movie proper that it was all squished and the same hints in TLJ's trailers was the same old bait without a meal. But here it is. Luke Skywalker hates the Jedi and explicitly calls them out for making themselves into "special people" power fantasies when the Force is a part of the universe that everyone has and shares, and he also totally might have been about to murder the "bad guy" in cold blood for the crime of being a scared teenager. Rey turns out to not be some dumb fucking chosen one of prophecy repeat, but is just a person who has taken charge of their own fate. Snoke is some shlub who got where he was by abusing the quick and easy of the dark side, and yet was raising Kylo Ren to be a synthesis of both light and darkness and also then gets fucking destroyed without so much as a fight. Poe being a reckless absolute individual Hard Man Making Hard Choices is a bad thing, because when you are operating as a group rebellion disruptive heroes who think they're invincible get everyone killed. The New Republic's "goodness" is functionally evil itself, because it plunges the galaxy straight back into a genocidal war after working so hard to get out of the last one.
And then there's Kylo Ren. Oh god, Kylo Ren. Back in TFA I thought his motive for killing Han was one of the best things about the film, because it was a villain motivation like that of Berserk's Griffith with weight and some scariness behind it. Kill the past is the theme of the whole film and what it intends to do for the franchise, and in this Kylo fucking embodies it. He gets it. He understands the endless cycle and wants now not just to sever his personal ties, but everyone's ties to the bloated past of the Star Wars galaxy. He transcended the inherent flaw in the philosophy of the Sith, the hypocrisy that embracing the dark side for your passion destroys that passion. Instead, he's embraced the dark side for...nothing. The void, the heady pure nihilism that can allow something new and unconnected to the bullshit of Empire and Republic to grow. And if the third movie in this trilogy in any way involves Kylo Ren using the First Order to crush the rest of the forces in the galaxy before turning it on itself and blowing up their dumb superweapon without a fight, I will endure any number of emo teen references in retaliation for my love of him as a villain.
Also, the FTL suicide jump was way cooler than the low-power DS shots or the destruction of the Death Stars. I got chills seeing the mountainous story roadblock of Star Destroyers just...disintegrate under the power of it, black space turned white in total silence.
They definitely should have killed Finn and otherwise rethought the whole of the Crait section. Luke's trick was a badass and appropriate way for him to go out (while also being, if you didn't catch it, so in tune with the force that he saw Tatooine's binary sunset on a planet with one sun which is neither of those colors). Letting Kylo just Obi-Wan him would have been dumb, but boosting his connection to the force until he joined it was the correct way to "kill" Luke.
I was fond of the "subtle" anticapitalism of rich people playing both the Republic and the First Order while living it up on a planet they stole.
But whether you all liked this movie or not, I hope you all see where its coming from. This movie is a purge of the curse of Star Wars upon itself. This deconstruction is necessary and should have begun a long time ago, and even if you hate this film, take some solace in the fact that it has opened up new ground for the third film and Star Wars media yet to come. Hopefully.
