“We’ve always been a show that combines gritty realism with moments of humor — I think you have to have both,” Franck said. “I don’t know that the show is darker, but it certainly keeps that gritty sense of realism and the horrors of war and the horrors of some of the events that are going on in the world. We don’t shy away from those, we don’t tiptoe around them, but at the same time … it also has moments of humor, moments of joy to lighten it.”
