Star Wars as a franchise is in a very weird place. While its TV department is working fine with the release of the latest season of Clone Wars and introducing The Mandalorian to canon, feature films have been questionable and created a division in the fandom never seen before. Fans are really not digging some of the decisions made by the filmmakers with both The Last Jedi and The Rise of Skywalker collecting mostly mixed and negative reviews.
While some audiences enjoyed the movie, the hardcore fans asked way too many questions for the studio to ignore. The plot of the last cinematic entry in the franchise was a mess akin to a swiss cheese wheel with enormous holes in it. One of the biggest issues fans and even casual moviegoers had with the new story is that J. J. Abrams decided to bring back Palpatine. The decision was probably made by a committee yet Abrams put efforts in defending it.
The studio definitely heard the fans complaining about the unexplained origin of the old (or new?) Emperor who was hiding on a distant planet obscured by some space magic and debris. The powerful Sith explained his reappearance in the story by saying that the Force has mysterious abilities “some considered to be unnatural”. It was a quote that thousands of fans tore apart. Really? Unnatural? Really?
Turns out, there is an explanation that is now canon. Whether it was a haphazard attempt to bring some sense to the trembling story of the Rise of Skywalker or a pre-planned idea that was just too late to the party is still a question that we will need an answer to. As for now, we can discuss how Palpatine was alive and well after being exploded twice in Return of the Jedi.
The novelization of the movie
In the novel, the fans will learn that Palpatine was just a clone of the Sith lord and was just a puppet controlled by the Sith collective. The clone is too weak to contain the cosmic power of Palpatine capable of destroying hundreds of ships with force lightning. It is something that Kylo Ren points out saying that he will not last long in the failing body.
The loose ends will be tied and Disney will satisfy some of the fans while preparing for the next trilogy in the Star Wars universe to hit theaters somewhere in 2024. Are you satisfied with this explanation?
