How is it possible to be tired of zombies? You would have to put some actual care into thinking about zombies to begin with. Zombies don't really strike me as villains or even antagonists of any kind (i'm talking about those brainless Romero Zombies not things like Las Plagas from RE4) because they cannot form opinions or ideas.
Zombies are more like environmental hazards than actual enemies.
