I liked this movie, but I didn't love it and I was primed like crazy TO love it.
I love everything Adam Driver did with his character in this entire trilogy and his and Daisy's performances are the heart of it, without a doubt.
I definitely didn't want Ben Solo to die, but if that was your direction, I think it could have been handled in a more heartfelt way and I am FAR from alone in feeling like this. He had no help/advice from force ghosts after his turn back to the light, Han was only a memory, and they don't even give Rey a few seconds to grieve him after he vanishes. I'm not open to any "He became one with the force, she'll see him again!" comments because maybe that's so, but what was presented on screen gave us no closure and left a lot of people feeling empty and hopeless.
Yawn @ Rey Palpatine, also. I found it more profound when she was Rey of Jakku.
I think it was a mistake to bring back JJ, tbh. He's the one that declined Episode VIII and they shouldn't have gone back to him.
