I don’t think many would be interested in slice-of-life on Tatooine type of film.
Not that it’s got anything to do with Rogue One but… that’s like saying nobody likes westerns. Just think any good western story but with blasters instead of sixshooters, Tuskans instead of bandits, speeders isntead of wagons, Ben instead of Clint. Basically the opening act of Star Wars then 😉
