Finally, I’m somewhat amused at how much faith you put in a man who is famed for his inability to stick the landing of his stories, when he has to do it now not just for this trilogy, but for the entire Star Wars saga.
This is why I looked forward to TFA with guarded optimism, but was surprised and disappointed to experience an OT rehash in a universe rife with possibilities. I expect nostalgia and sentimentality will take the place of storytelling in Episode IX, so people will leave the theater feeling good, but ultimately the conclusion will feel empty upon subsequent viewings.
I don’t believe that this is the end of the saga, though. Disney isn’t going to close the door on future numbered films. Too much money there. Kylo and Rey could have a Force-sensitive superbaby to keep the bloodline going (assuming we don’t get a Rey retcon in IX that makes her a Skywalker).
