What would be any reason for this to lose theatres? Isn't it doing spectacularly well everywhere?

Some theaters only have one or two screens and are in small towns. Probably wouldn't need to keep it longer than a couple of weeks in a small town. Everyone would have seen it already. Probably twice if they wanted to. Generally they would switch out movies faster so they can keep getting the big ones.
