Which are you personally more afraid of: mutants, zombies or space aliens?
I don't understand zombies, because it seems to me that somebody who is dead and comes back to life should be so grateful that he's here living again -- why would he want to eat up other people? I think the first thing he'd do is get a nice apartment and figure out how he can make a living and get a girlfriend. I'm personally more afraid of what's really going on with nuclear weapons and things like that.
In underscoring the lack of forethought on the part of zombies, he fails to mention that most human characters aren't much smarter. A case in point is virtually every horror flick ever made. You just know that something wicked is behind that door, but you can't help but open it anyway without a crucifix or a wooden stake in hand, don't you think?
Or don't you?
