Why zombies?
The current wave of zombie entertainment began with 28 Days Later, moved on to Zack Snyder’s remake of Dawn of the Dead, which spawned a remake of Day of the Dead, and, from George Romero, Land of the Dead, Diary of the Dead and Survival of the Dead. Pride and Prejudice and Zombies was a hit novelty book, and suddenly zombies were everywhere, culminating in The Walking Dead and now World War Z, which became a smash hit in spite of a wave of negative buzz.
