To analogize: If the original Star Wars movie* was The Dam Busters, then Rogue One is The Dirty Dozen. While the morality in original trilogy might have been black-and-white, in this joint it's very, very, gray.
I liked it better than The Force Awakens. Compared to that film, Rogue One doesn't feel like it's trying so hard to be a Star Wars movie. From a wargaming perspective, I'm sure you'll get plenty of scenario ideas from the many battles.
Like I said, go see it.
