I'm interested in everyone's take on this. It's just my opinion for what it's worth. Seems like every "living dead" type of movie or TV show, where the dead comes back to life, out of their graves, etc. is always explained by way of a "chemical spill" or a "virus" or something similar. It's almost like they're trying to make it realistic or believable by coming up with a valid reason why something like that might occur. I would like to see the dead rising and walking the streets just because. Not because some boob accidentally leaked chemicals into the earth or because of a sickness. For me, that takes the darkness out of the idea. It makes it too conventional. I realize I may be in the minority here. What do you guys think?
