Did you know that May is Zombie Appreciation Month? I didn't either, but let's face it zombies deserve their own month after all they have been scaring movie audiences for years. Everyone can remember their first encounter with the living dead on the big screen. I believe mine was "Night of the Living Dead". a true American masterpiece. Since that classic was released in 1968 zombies have plagued movie theaters in an effort to scare us, entertain us or at least make some money. So what are the best zombie movies ever made? The Post Chronicle has ranked the top 13 zombie movies of all time. Did your favorite make the list?
