Wrap the series? Bite your tongue. I'm expecting Carl's grandkids to be killing zombies before I go.
The franchise will live on. The possibilities are endless. The game, comic, and TV show have only shown what's happening in Georgia. What's happening in California or Texas or Michigan? Hell what's happening in Europe, Asia, or South America? Though the series will end some day, the spin-off possibilities are amazing. I fully expect a movie franchise to come out of this as well...and it's needed. It's already pretty clear World War Z is going to suck balls.
