Starz is going to broadcast a documentary starting in October about the zombie phenomenon.
I first watched Romero's 1968 b&w classic on Chiller Theater, hosted by Bill Cardille. The 1978 classic, Dawn of the Dead, which I saw as a college student, was shocking. We drove the long and dark Route 88 back to school more than a little creeped out.
Romero has used zombies as metaphors for our mindless consumerism. Personally, I see them as representations of our true selves. Unhindered by laws, rules, morality, ethics, our animalistic natures are unleashed. Most of the time, I just enjoy the pretend carnage.
Whatever the attraction, the zombie genre doesn't seem to be going away soon.
