One of the complaints you see online from the angry Star Wars fans who don’t like the Sequel Trilogy is that it’s not a repeat of the Original Trilogy, just with older versions of Luke, Han, and Leia as the main characters. Despite Return of the Jedi being an ending for their story, some people just wanted VII to IX to feature them, instead of new characters for a new generation of Star Wars fans who will keep the franchise alive long after these “true fans” die off.
In an interview with Rolling Stone about The Rise of Skywalker, JJ Abrams addresses this:
Another criticism, from older fans, is that these movies aren’t really about the original heroes. Did part of you want this to be more of Luke, Leia, and Han’s story?
It certainly could have been their story. But it felt like the way to use them was to be in support of a new story. The great thing about Star Wars fans is they care so much. And even those who are the most cynical or the most negative are still people who, for the most part, embrace what’s being done, even just as fodder for debate. All I can say is that the main characters in this trilogy felt naturally connected to those characters that came before.
The interview also reveals that JJ had a meeting with George Lucas prior to beginning work on The Rise of Skywalker, and he also addresses the Rey “Mary Sue” complaints, “Yeah, spooky, right? [Smiles] It’s a fair point. It’s not an accident.” Based on the spoilers that are out there, people can probably connect the dots to figure out what he meant by that…
