Both shows are soap operas where someone gets eaten by zombies periodically. No real attempt to explore the universe they are in. It might be interesting to go back to the initial premise and drop these boring folk. Show what happens to a nuclear carrier when the plague hits - sort of like Last Ship.
What happened if some country figured it out quickly and sealed its borders and took out the initial walkers? What happens in colder states where they freeze in winter - like in the World War Z books?
Something else than angst, nuts and chomping.
