ugh. Zombies. Never understood this fad. (Did enjoy "Cell") Anyways, IMO Mr King wont "end" the show even if he was contractually capable of doing it. What message would that send to people who later might be looking to pay money to adapt his stories? He also is on record saying he is all for people running with his source materials. The ratings have been a bit troubling for viewers. The total number is still decent. However the attrition and trending look very rapid. I wouldn't be shocked to see this series not get renewed and kind of hang out there unresolved forever... unless one of the streaming services pick it up.
