If you want to criticize it, fine. I just don't think it's the huge deal you make it out to be. It's one little line said by a very minor character.
One line that neatly symbolizes the much bigger problems that pervaded the movie, the way that the film failed to earn its assertions of Superman's heroism and greatness and the way it tacked on obligatory story beats rather than having them develop organically from plot and character. (For instance, there was no reason why Zod landed the ship in Metropolis, because Superman had never even been there at that point; it was just arbitrarily chosen because Metropolis is where you expect the climax of a Superman movie to happen.)
