Plot details are still under wraps, but we know that the film will be set a whole fifteen years after the events of The Rise of Skywalker, and that that Rey will be a "powerful Jedi master" running her own training academy when we catch up with her.
So basically what the sequel trilogy should have been? Why can't we just jump to another era of star wars. Give me the old republic or jump 100 years into the future where Rey, Luke, etc. have become legends used to build up the story.
Honestly tfa is my least favorite of the trilogy. Just refused to break new ground, and did a lot to sully what it retreaded. tlj at least took risks and I didn't like it, but I respect it. And ros was the best theater experience I've ever had (had the full theater to myself so I was free to exclaim about the bullshit to my hearts content, and I had bottomless spiked milkshakes, so I did exclaim to my hearts content)
