I actually dread WWZ because Walking Dead stuck a stake into the heart of the genre. To mix a metaphor. George Romero is spinning in his grave. And he's not even dead yet.
Zombie shows have joined the Choir Invisible. They are pushing up daisies. Bought the farm with the barn full of undead loved ones. It's gone shaved-gymrat-deputy-mantits up. Pining for the Georgia quarry fjords. They've bleeding demised. They have gone to meet its maker. They've passed on. The joke has ceased to be. It is no more.
It is an EX-meme.
