Star Wars is a universe that between Legends and Canon is like what, 4000 years or more? Why not just do something new? The Mandalorian doing well should be sending the message that fans want new original content, not rehash and repeat of similar storylines. I liked the last few movies but that's because I literally loved all the fanservice most people hate. I am that guy. (Sorry) That being said, a new, original story that wasn't simply a rehash of the same morals and ethics through the same plot devices would have made for a much higher quality set of movies overall. They can do that now, or in the future, so why not do that? It just seems odd to me.
