15 year Time Skip? I personally think they should of time skipped about 50 or 75 years into the future. Have a whole new "Skywalker" Character we've never seen before and new villains. I think the story should be an older Grogu building the new Jedi Order but maybe that's the plan later on. As for Rey getting another shot. Look as an OG Star Wars fan, I think the new Trilogy was the weakest of the bunch. They missed up plot by not making Rey related to Luke. Not writing good endings for Han, Luke or Leia. Also yes they did drop the ball on Finn which after "Awakens" they were building him up to be a Jedi only to just make him a regular human. Also making her somehow related to the Emperor was one of the laziest twist to me. It was like done for shock value. As for her returning.
I think people are confused about something. The Star Wars Sequel Trilogy did not flop. It made over 4.5 Billion between 3 Films. Matter of fact "Rise of Skywalker" was the last Billion Dollar Film before the Pandemic Hit and it took 2 years for "No Way Home" to break that record. "Rogue One" was a success because "The Force Awakens" smashed sh!t and it came right after. "Solo" was the only film that underperformed and that was because they didn't bring Harrison Ford back who's still alive. People weren't sold on seeing a Young Han Solo when they just saw the real Han Solo in "Awakens". So in Disney's mind continuing with Rey is a good business move because of the success. This reminds me of the Prequels. A bunch of Older Star Wars fans saying "The Prequels ruined my childhood". LOL, acting like some losers. If a movie ruined your childhood you didn't have a great one to begin with. Those Prequels did exactly what Lucas wanted. Bring in a whole new generation. Now you have kids that grew up on Anankin and Jar Jar instead of Luke and the Ewoks. This is why the "Obi Wan" show was made and a success because the Prequels Fanbase is now older. This is why "Askoka" is getting her own show because so many kids grew up on the "Clone Wars" Cartoon.
Well now the Sequel Trilogy fanbase is growing up too. Now you have kids that grew up Rey and Finn. My issue with the Sequel Trilogy was the storytelling just wasn't that good. They literally remixed "A New Hope, Empire and Jedi". It just lacked any originality but I also realize the sequel trilogy was not made for me. It was made for new kids growing up today. Hopefully "Star Wars X" will be better. But I'm actually not shocked they are continuing with Rey. The Sequel Trilogy was a success regardless of the criticisms. Also there was way to much crying online about these movies. It wasn't that serious but people were acting like it was end of the world, lol. Some Star Wars Fans can take it way to far with their emotions and how they want these films to go. When Disney brought Star Wars I was the main one this very board that said they should Follow Lucas's outlines. But people were capping for Disney saying saying they can do better than Lucas, LOL. The Prequels are lightyears better than anything Disney has done. (Though I did enjoy Awakens (A new Hope Remix), Rogue One and Mandolarian)
