I think they have killed off too many characters.
I think they took the "who will live, who will die" ploy too far. At some point if you kill off too many loved characters or too many loved characters leave fans lose interest. Carol and Daryl are all that are left. Rick is gone....apparently Maggie, Carl, Glenn, Lorie, Shane, Sasha, Sofia, T-dog, Andrea, her sister, Dale, Hershel, Beth, Abraham, Morgan, his son plus tons of others they have befriended. I don't think Enid, Rosita, Eugene and Ezekiel and little Judy can carry the show. I just don't care that much about these characters.
