We are all familiar with Zombies. It is a real popular genre designed to make the viewer feel powerless and unsafe. Recently there has been an explosion of medical pandemic movies which emphasis the vulnerability of our modern soceity. In the bad drop of many of these medical "terror films" are zombies. Lifeless soulless creatures whose main purpose is to live, eat living things, and terrify the living. But when we look at it, is this possible or is it fantasy?
If they are truly living dead, they could not be active for any major length of time due to what we sciency people like to call decay. Therefore they can only exist through magic and therefore, magic should work against them - i.e. they can be ended by applying salt or meat broth to them. I get bored with people gaming this by giving decaying things superspeed and such. Not rational - just a way to artificially make them scarier. My thought:
if if you want them fast make them ghosts or werewolves/weretigers.
