I went and saw it. It wasn't really worth it. It was better and more coherent than the prequel movies for sure, but there are lingering problems.
1. Some of the actors like Finn's love interest, the suicidal admiral lady, and Mrs. Giant Nose were awful, or badly cast. Finn's love interest (whatever her name is), had the most awkward and flat introduction scene. Suicidal Admiral Lady (whatever her name is), just felt like an office manager trying to act. Nose lady was too ugly for film, and hence poorly cast.
2. Why the hell is the Republic on the run from "The First Order"? They beat the Empire 30 years ago. It was a deciding victory. When RotJ ends the Empire's entire fleet is pretty much wiped out. The movie fails to explain where The First Order, or Snoke came from. This could be fixed in the final movie, but I'm not sure if they'll get around to it.
3. Why does Luke want the Jedi to die out? Another thing the next movie needs to answer.
4. The whole "I know we're on the run from the Empire, but let's just take a small craft to a casino planet, and hope the First Order doesn't notice us escape and return", thing was a pretty big plothole.
5. If ramming the main enemy ship would have won the battle, then why not just put a single pilot in the Mon Cal cruiser, and do that all along?
6. 100 tits lady was cringy and that micro-scene should have been left on the cutting room floor.
7. The chase sequence with the racing dog things didn't make any sense. They are powerful enough to barrel through rock solid walls, but the people riding them don't get hurt or knocked off? What?
Now for the things it did right...
1. Having Rylo kill Snoke in order to succeed him makes perfect sense. I did not see it coming, but that's actually how Sith Apprentice/Master relationships work. In order to become a master the apprentice has to kill his master.
2. Having Luke use a force projection to fake out Rylo was great. That shoulder brush was hilarious.
3. Adam Driver isn't a skinny little kid anymore. Having Rylo be this skinny little dweeb as a Sith just didn't make sense. It's like when the kid from That 70's Show was cast as Venom in Spiderman 3. It just doesn't work.
Overall I give it 2.5/5, with the ability to be a solid 3/5 if the following movie answers lingering questions. It's really hard to judge the middle movie to an intended trilogy. Empire Strikes Back had a lot of issues until RotJ answered and completed the story.
