I must be the only one who liked the Casino scene. It sets up some galaxy world building, (perhaps) sets up a plot point for the next film, provides some relief from an otherwise downer of a film and reinforces the film’s overall theme of failure and learning from your mistakes.
On another note: I do wonder if scenes of Leia shot for this film won’t be used/reworked for the next one. They might have to be clever with what they have but it could be doable.
I know they have lots of deleted scenes, maybe they are going to see what they can do to incorporate Leia into the next film. I’m sure their not, based on what Rian and Kathleen Kennedy said, but you never know. I thought at one point they were based on Carrie Fisher’s brother stating it, and Lucasfilm denying it, so who knows.
