[quote="mR.cLeAn":f66f0]What would you guys think it would cause this to happen[/quote:f66f0]

I dunno, I like to think it's because there is no more room in hell, and the dead are forced to work the earth....(That's pretty much a direct quote from both Dawn movies - Both times made by the same actor, Ken Foree)

I think that's what Romero is getting at....It works well with all the social commentry and themes that are prominant in the dead series...As if humans are by majority, all naturally evil and so hell has filled up....
