One of the bigger disappointments about The Rise Of Skywalker is precisely how badly they botched making that point, when it was absolutely key that they did so. The exact question, the very notion that bloodline is THAT important, when legacy can (and should) be and mean more than simply blood and familial connections - the first two movies laid a lot of road to arrive at a destination where that entire question is answered definitively. The legacy of the Skywalker family SHOULD BE, by the end of Rise of Skywalker, that the family name doesn’t need to be tied to blood in order to have meaning and power. That by the end of their saga, the ultimate lesson they’ve passed on is one that is inclusive, hopeful, and meaningful. You can be what they were, and that name can apply to you, because it’s no longer just the name of a family, but the name of a philosophy, or an outlook on life, and living.
Rise of Skywalker didn’t get anywhere NEAR that, and while I don’t believe that sequels can retroactively ruin the movies they follow, that the quality and status of that preceding film is what it is, and that work stands on its own FOR what it is, no matter what - I do think that Rise of Skywalker dropping that ball as hard as it did makes the road the preceding two movies laid down a lot less stable. It puts a lot of potholes in the sequel trilogy, basically.
Smaller disappointment: Lando got the Falcon back and there was no real moment of significance attached to it. I think there was barely a reaction shot, in fact?
