I never saw Star Wars as silly. Campy in some parts? Sure. I mean his inspiration was like the old Buck Rodgers serials. Formulaic, simple tales of right and wrong. Heroes being heroes, and villains being villains with action and daring.
I have no idea how how he managed to write Star Wars so well (even with its faults) and then completely screw up any other scripts he did for Star Wars.
The reason I have faith in Disney is they are not beholden to just one person. They are beholden to Star Wars and everyone involved wants to make it great. I just saw the documentary on Zootopia and how their writing process works with lots of feed back and round tables to get the story to work right. While we can nitpick about several parts of the new film, it was a solid, simple story. No space legalese. No over done exposition. No personal relationships being forced. Etc. I have positive hopes that they will continue improving their writing, and thus the films will be even better. Look at their last several animated features and they have all had solid story telling.
