The question often comes up will it be Science or Nature that brings about the undead? It is tuff to tell. Although there are no doubt ably test going on in government secret lab's across the world working on experiments that could lead to the undead becoming a reality. We also have to ask ourselves when will Mother Nature get pissed enough for what we do to the planet to turn on us? Turning us onto our selves as flesh eating zombies with no remorse.
28 Days Later taken the Science approach to the undead. Creating a Rage virus which is accidentally unleashed on the population of Europe.
Another question that comes up is will the zombies be slow and uncoordinated in their movement or will they be fast and seem almost super human?
28 Days Later takes the fast Zombie approach. Being chases at high speeds through streets, buildings and across open fields adds a new level of terror of what is to come.
28 Days Later is a must see and probably have seen a million times for anyone interested in Zombies.
