I’m sure the movie will be fine, I just think it’s a cheesy line. A New Hope had plenty of cheesy lines, but the overall tone of the movie allowed for it because it was a cheesy movie. Rogue One is trying to pass itself off as a gritty war movie set in the Star Wars universe, and if that’s what they’re going for, there’s no room for cheesy lines like that.
Doesn’t mean it has to be that way for the entirety of the movie. It still has to feel something like Star Wars.
