I'm going to mirror Landlord a bit here.
The good:
-Snoke was fantastic, so well done. Not a sith but powerful! Lightsaber unnecessary because he is so powerful and all knowing. Then, he dies in an amazing scene. Seriously did not see that coming, I really expected him to like regenerate or something. But no, just flopped over in two pieces. The fact he was nobody actually made it better, I'm glad he wasn't Plagueis, Sifo Deus or Gallus Rax. His throne room was awesome, the lightsaber battle was also slick as hell.
-Daisy Ridley, really nailed the vunerable lost soul with raw potential thing. Love her, can't wait to see her come full circle.
-Adam Driver, homerun. LOVE that he is being handed the reigns to be the big bad after all the speculation of his conflicted position. Not even Vader got to be the true big bad, not once. Kylo Ren is a great character.
-Chewbacca was about perfect, not too much but just enough.
-Leia really got to shine in her swan song.
-Crait was an awesome planet and visually it was just beyond fascinating.
-Holdo and the suicide lightspeed shot through the destroyer was an absolute achievement. Beautiful. In retrospect it's almost a shame they didn't have Leia go down with the ship and have Holdo take her place as General. Hindsight 20/20 unfortunately. That and Laura Dern was terrific, would have liked to see her in the next.
-FINALLY, a freaking Star Wars movie remembered what Yoda is SUPPOSED to look like! Seriously!
-Poe is such a fun character, funny but courageous and all that jazz.
-Luke force projection battle was too good. Man Mark Hamill still had it, how cool to see that after all this time. And was it not just freaking perfect to have him chuck the lightsaber over his shoulder?!!?! 2 year wait after TFA and he just goes "Meh...junk. leave my planet". Force Ghost Luke is going to be bone chillingly cool to see in 2 years. Damn, Luke was awesome! He was still Luke but like more badass than ever!
The bad:
-2 movies, and it is BEYOND evident that Captain Phasma was merely a way to sell a chrome stormtrooper action figure. What a complete waste. You could have random stormtrooper #7 with a different colored shoulder pad to indicate rank fill the role in either movie and literally nothing would be different.
-John Boyega as Finn is good, don't get me wrong. But they clearly had no clue what to do with him in this movie.
-Benicio Del Toro, unecessary.
-The whole Casino subplot could have been cut and made the runtime shorter and nobody would complain. Too bad, it could have been a lot better. Finn and Rose could have simply infiltrated the First Order ship without the detour, would have been way more interesting to watch an extended infiltration mission instead of lollygagging around with the race horses etc. Oh well.
-We have all wanted to see Leia do force stuff.......but that was straight out of a Stanley Kubrick idea journal. Like that took me out of it honestly. Not a fan of that scene, probably my biggest gripe since the decision to insert Hayden into ROTJ.
-Still no Knights of Ren, after all the waiting.
I'm sure I'll think of more, that was a lot to digest. SO much happened but almost nothing happened, heard it said that way yesterday and it rings so true. I want to see it again to truly rank it, but it's towards the top.
