Last humans are tearing themselves apart & then zombies show up to finish the job
Day of the Dead is another classic zombie flick by the auteur of the genre George Romero. The apocalypse has already happened and there’s only a few human survivors. What’s happening to them? They’re coming apart at the seams. You wouldn’t think that would work because there are hardly any zombies until the very end of the movie but it actually does. When the undead finally show up there are some great special effects of them eating people.
