You miss out a lot. There is barely any zombies in the show. It deals mostly with things that would occur between human in the context of apocalypse. Distrust and love, losing a loved one in an instant and the following despair, not giving up and loneliness when no one can afford to care, and revenge and other stuff. It’s mostly a character story, and there are barely action scenes.
I watched an episode and a half of that and gave up. Had enough of zombie movies. They're all the same.
