I can't really make fun of zombies. They're not liars. They're not cheats.
My stories are about humans and how they react, or fail to react, or react stupidly. I'm pointing the finger at us, not at the zombies. I try to respect and sympathize with the zombies as much as possible.
I also have always liked the monster within idea. I like the zombies being us. Zombies are the blue-collar monsters.
For a Catholic kid in parochial school, the only way to survive the beatings - by classmates, not the nuns - was to be the funny guy.
If I fail, the film industry writes me off as another statistic. If I succeed, they pay me a million bucks to fly out to Hollywood and fart.
