Every time a zombie apocalypse (or comparable outbreak) occurs, characters have to learn the "rules" of the zombies in that particular world. Does this mean no zombie movies exist in this universe? It's a world where Night of the Living Dead never got made? But if that's the case, have all other movies except zombie movies been made? Are these characters familiar with Godzilla movies and superhero movies, just nothing with zombies? What about movies that reference zombies but aren't zombie movies?
Do vampire movies exist in this world? Was the Twilight series a worldwide phenomenon but people still have to be educated about the rules of these other fictitious undead creatures they're encountering? No character is ever like, "oh yeah, zombie apocalypse -- don't get bit, blow up their heads, standard Zombie Rules. Yeah we got this."
If these characters are completely (rightfully) baffled by the sudden existence of zombies, can we conclude that the word "zombie" never existed in the universe of this world? Otherwise, why wouldn't they immediately be like "hey guys, there's zombies everywhere. You know, that standard word that exists? It was a fictitious concept but now it is real."
Are "zombies" still enemies in Final Fantasy games? Could a really tired person at work describe themselves as a 'total zombie'?
Did The Cranberries ever release the song "Zombie" in this world?? If not, did they still release "Linger" and "Dreams"? Is this a fictitious universe where The Cranberries still existed but had a marginally less successful career because their second album never had a breakout single? Or was a different song from that album a breakout single in this universe? Or was it the SAME song, just about werewolves or something?
WHAT IS ROB ZOMBIE'S LAST NAME???
While the entire Southern United States is a post-apocalyptic barren wasteland of destruction and backstabbing haphazard pseudo-gangs, is everything on Iceland just like, totally fine? Or did an infected person get on a plane or a boat to Iceland, start biting people, then the pilot landed the plane successfully and the infected people ran off the plane and ravaged the island society?
Surely there's some islands that are totally fine, right? Are Madagascar and Papua New Guinea the new world superpowers? And if so, can they just go on living normally while knowing their closest terrestrial continents are overrun with swarms of the undead and tiny pockets of scrambling desperate survivors? Probably, right?
