Had a night to sleep on it and think it over more.
Terrible. Unoriginal, which is the going rate for Hollywood these days.
As others have said, just like in TFA they are throwing far to many angles into 2ish hours and seeing them underdeveloped before being cast aside too quickly. The damn movie was all over the place. And it wasn't the cast or dialogue that killed the movie (i think those aspects are great), its the contradictory nature of the major plot lines.
It was absurd to cast Snoke as an incredibly powerful force (think Valkorion from the Old Republic era) who literally manifested the force connection between Ren and Rey and wielded power effortlessly, succumb to not being able to see Ren's intentions. So in that light it was a complete rip off from the Jedi Order failing to see Palpatine/Sidious because of arrogance and then again Sidious failing to see the conflict in Vader because of arrogance. "Your overconfidence is your weakness". Sorry, been there, done that. Unoriginal. And on top of that, we have no background on Snoke. He's cartoonish character who, like many of the plot points is vastly underdeveloped.
The political jabs are subtle but again, another aspect that has corrupted Hollywood. Star Wars was simple. It's about good vs evil. You want to branch out, fine, but do it without the underhanded political nonsense.
Mark Hamill did a tremendous job. Disney did a great job f***ing up his character arc. You want to kill Luke off, fine. But do it in a way that hasn't been done before. Again, we have the most powerful Jedi who ever lived force transfer his image across the galaxy (which was cool as hell to be honest) and then die as sort of a martyr/sacrifice ala Obi Wan because he was "at peace" with his demons finally. You raise the fans up with brilliance and then donkey punch them with crap we've all seen before.
Rey is a "nobody". Yeah, so was Anakin. Or it was a red herring and she is in fact from a great lineage. Either way, it's not original.
Leia has super powers. Never explained and unfortunately with Carrie Fisher's death we'll likely never get a good backstory.
Hall of mirrors was basically, stop looking back and get on with your life and future. Very trippy. I liked this part, given the simplicity.
And lastly, the Jedi must end. Luke said it, Yoda said it and then burned down the Force tree. Then it's strongly hinted that just the opposite is in the cards for the future given the ending sequences. But are there really Jedi or do we just have a conflicted good girl vs a conflicted bad guy trying to find some semblance of balance between the light and dark and a future host of force sensitive kids looking outward towards their destiny.
