For survivors of the zombie apocalypse, hopes are not lifting. As others try to keep their mind on practicalities, former policeman Rick Grimes seems increasingly on edge. As his behavior grows more and more conspicuously eccentric, other group members worry that he is putting them all in mortal danger. This already popular graphic novel series is certain to be bolstered by AMC's new Walking Dead television drama, which premieres on October 31st.
