I'm a huge star wars fan but I just wish these resources could have been allocated to another story.
I'm tired of the Death Star and all its different iterations. This story just seems so unnecessary. We already know what happens to the Death Star, The Rebels, and the Empire and also what happens to the organizations that form once they fall. All these events are too close together for me to care.
I would have much preferred a story that stands on its own set in the Star Wars Universe.
Maybe have a movie that takes place during the end of New Hope all the way through Return of the Jedi from the perspective of a young Imperial officer that somewhat sympathizes with the rebels and doesn't agree to all the things the Empire does. We could see how the Empire internally dealt with the destruction of the 1st Death Star, how the reacted to the idea of Luke Skywalker and the force, and basically the internal power struggle on the direction of the Empire which ultimately leads to its downfall.
Rogue one is nothing new. It's just a Rebel mission from the originals without Luke Skywalker. We've already seen the battle of Hoth, Endor, rebel space combat etc.
I want to see how the Empire works because we've always been led to believe that they were just a bunch of robots that took orders and had no personality but now as more content comes out we see that's not the case.
Anyway I'm still looking forward to more star wars.
