Most zombie flicks I’ve seen are American, and most zombies I’ve seen are the result of a virus of some sort that’s more or less accidentally released amidst the general population. Usually the infection makes everyone ravenous for human flesh and gives them unnatural strength
and the eyes of a serious caffeine junkie in withdrawal.
Well, nothing wrong with that, I say! To each their own. Personally I prefer my zombies undead, merrily groaning and shambling head-first into the same stretch of the garden fence over and over again.1
