Apocalypse by: Fast-as-hell zombies 

Students of the varying types of zombies in popular culture know that the most terrifying of them all are the ones who can run. Sure, the stumbling, bumbling flesh-eaters are scary and threatening enough, but unless you’re some type of athlete, you’re just not going to make it in the world of zombies who can run. You don’t need to be swarmed by a crowd of them. Just one could run your ass down like it’s Richard Sherman. 

Just when you think the apocalypse is under control, these swift zombies can muck it all up again. Look at 28 Weeks Later, which, in my humble opinion, is the superior of the two films. The Americans swoop in to save the Brits (you’re welcome), only for another outbreak to begin because of a couple of overconfident children (shouts out Imogen Poots). Your thorough zombie apocalypse plans don’t mean a damn thing if the zombies are swift.
