I’d say that the most satisfying aspect was seeing Harrison Ford and Carrie Fisher in character again. I didn’t like the death of Han Solo at all and it ruined a lot of what I did enjoy about the movie, but overall I think it was one of the better Harrison Ford performances in the last twenty years.
I agree, I thought he turned in a great performance. And I didn’t think she had much of anything to do in TFA but I really liked her in TLJ.
I also agree with both of these posts (except about Han’s death, I thought that was perfectly executed [heh] and was necessary for the story).
