Why are people so obsessed with zombies?

There has been a trend over the past few years for people to just LOVE zombies. I mean zombie everything!! We have zombie movies, shows, videogames, books, even zombie themed runs in high demand. But why? I can’t stand zombies. They’re evil dead creatures that want to kill you. I don’t see the appeal at all, they creep me out! The trend has moved from vampires to zombies lately and being truthful, I don’t have a like for either one. Can someone just explain why there is so much hype around zombies? I’ve even heard people say they WANT a zombie apocalypse! (that’s ridiculously stupid…....)
