I can tell you this article is WRONG about why we love zombies. and by love, we mean, we fear them and we love the adrenaline they produce.
Channeling my evolutionary psycho/bio/social – ist… it’s because mostly mindless stuff has chased us/stood in our way of survival for eons.
no really. we fear the random beasts that come to chase us from the stuff we need/love/want. The more human it appears, the more dangerous it seems. I suspect this holds for vampires too. They just look like creatures that would eat us and are smart enough to trick us.
For all these creatures the fancy stories are just gloss on a really simple thing… we fear the unrelenting beast that can’t be talked out of taking us out.

I however remain in the camp of those that theorize that they are not so much a personification of various phobias lurking within the unconscious of the population but rather a projection of the Jungian Shadow. We are scared of zombies due to the fact they display a dark side of us – consumerism. The mindless masses living day to day in a state of unexamined habitual activity never able to satiate our endless hunger for more. They are a fear of ourselves. A fear of what we as a collective have become. A fear of what we may become. And it’s great to see Woody Harrelson doing more movies!
