Give em enough time, and they can eliminate Daryl and Rick too if need be. Fans might be high on them, but give enough time and it gets boring. Best if they recycle the formula and keep the momentum going by slowly introducing new cast member. Maybe an old witch doctor with some mystic power, to balance out the zombies. A touch of werewolf; a hint of vampire; and maybe a possible cure is enough to keep viewer excited. Of course we can't ignore the sexy dirt to bring forth the sex appeal; nudity/sex scene too. Hmm, maybe an occasional Bigfoot from an interdimensional portal.
