Wow, I can’t believe how much I agree with your original post and editing philosophy. It’s almost like I wrote it. The appearance of Tarkin and Leia left such a bad taste in my mouth that Rogue One is the only Star Wars film I haven’t cared to rewatch. And I found the Darth Vader hallway scene similarly distasteful. But I know there’s a lot to love in the film besides all of that.
I wish I had more to offer in terms of suggestions, but all I can say is that I’m interested and excited to follow the progress of this edit.
