There is talk of a WWZ trilogy. The ending gives a hint of at least a sequel.

As far as TWD is concerned, I'm angry that the directors didn't kill off the Governor at the end of season 3. If he is the storyline for more than 2 shows, I predict the next season will be the last. I mean, come on. The guy killed a group of soldiers, killed Merle, killed Milton who killed Andrea then killed his own people. Enough of this **** already. He's done enough damage. What next? He kills more people?? He's killed more humans than the zombies. The show has lost direction.
