Why are zombies so scary?
There are obvious answers to this question - however, as it's the season to delve deeper into horror and all it's gory glory, let's examine the reasons a little more closely...
They are dangerous - goes without saying really, apart from the odd zombie with a heart (their own, not one they've ripped out from the rib cage of an unfortunate victim) they are going to kill you. They have to, to survive. Their hunger is constant and well there's a lot of them and not many of you to go round! They'll fight to get their jaws wrapped around your sweet bones. Then of course, if you survive such an attack, odds on you'll end up just like them.
They hunt in packs - one zombie is bad enough, but hundreds? Slow or fast that's going to a be a nasty thing to see; a wave of undead clawing their way toward you, the sheer body weight could cripple your car, break down your doors, smash your windows and envelope you before you can even count them.
You can't reason with them - they are kind of one track - they only want your flesh or brains - that's it, they won't take a bribe, or be seduced into submission. Violence is all this monster knows - either you kill it, or it will kill you.
They are us - they are not from another planet - they are already here, because they are us. There are billions of people in the world - how long would it take for the majority to be infected once an infection starts? The Black Death killed over 4 million people in 2 years and that had an incubation period of 2-6 days. By the Spring 1349 it had killed six out of every ten people living in London! If a zombie bite turns a victim in less than 60 seconds, well that could be some truly terrifying math!
It's a nasty way to die - being eaten alive. Forgetting the Hollywood scenes of undead feasts, you only have to read the harrowing stories of of people who have survived animal attacks to imagine what it would be like, and to make you wonder what you would do yourself, in such a situation.
