I don't think any Star Wars film is an exceptional example of good writing, but Rogue One takes the "plot armor" to even more ridiculous levels. And then of course everyone still dies anyway, it's unsatisfying. I think that writing a movie for a bunch of disposable characters is an inherently flawed premise, especially with the audience knowing the outcome of their main objective. At least the Han Solo movie doesn't have that issue so it should hopefully be a lot better.
