Here is an interesting article from Simon Pegg arguing for a return to traditional zombie values. I have to say I agree with him.
The speedy zombie seems implausible to me, even within the fantastic realm it inhabits. A biological agent, I’ll buy. Some sort of super-virus? Sure, why not. But death? Death is a disability, not a superpower. It’s hard to run with a cold, let alone the most debilitating malady of them all.
More significantly, the fast zombie is bereft of poetic subtlety. As monsters from the id, zombies win out over vampires and werewolves when it comes to the title of Most Potent Metaphorical Monster. Where their pointy-toothed cousins are all about sex and bestial savagery, the zombie trumps all by personifying our deepest fear: death. Zombies are our destiny writ large. Slow and steady in their approach, weak, clumsy, often absurd, the zombie relentlessly closes in, unstoppable, intractable.
However (and herein lies the sublime artfulness of the slow zombie), their ineptitude actually makes them avoidable, at least for a while. If you’re careful, if you keep your wits about you, you can stave them off, even outstrip them – much as we strive to outstrip death. Drink less, cut out red meat, exercise, practice safe sex; these are our shotguns, our cricket bats, our farmhouses, our shopping malls. However, none of these things fully insulates us from the creeping dread that something so witless, so elemental may yet catch us unawares – the drunk driver, the cancer sleeping in the double helix, the legless ghoul dragging itself through the darkness towards our ankles.
What ever Hollywood tycoon thought Zombie 2.0 was a good idea needs to get out of the business. Not everything needs to get upgraded, death is elemental is does not need to be improved on.
