I thought Daisy Ridley (Rey) was quite good, and I liked her and her character.
I was uneasy about John Boyega (Finn) at first because I assumed he was the Affirmative Action hire, but I think he did a credible job.
It looks like Rey and Finn are destined for a romantic relationship, so it remains to be seen if they can bring the necessary emotions for that. Previous Star Wars films were just terrible at Romance, namely, Natalie Portman and what's-his-name.
I thought Oscar Isaac (Poe) is not quite good enough for his part. Bottom Line - I have zero emotional involvement with his character. Are Poe and Finn destined to become rivals for the hand of Lady Rey?
Kylo Ren is terrible. The character is unconvincing, and the acting (Adam Driver) is unacceptably weak.
In any event, I still liked the movie, and I watched it twice from beginning to end.
I have heard that “The Last Jedi” is Social Justice Warrior crap.
Finn’s ideal character arc of dying against the regime was interrupted by Rose’s stupid sacrifice that, if Mary Sue had not come to the rescue, would have killed all of her friends.
