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.
