Great article. Interesting about the zombie porn.
The problem I see with a lot of these thread is that people have seen too many movies. They expect that if the dead started to rise, they'd suddenly turn into John Rambo: Zombie Killer. When in fact, most people would hesitate, get frightened, or freak out completely when faced with a horde of partly decayed creatures covered in blood and gory wounds. And probably smelling to high heaven too.
I think people would be wigged out the first day, but they'd very quickly get used to thinking of zombies as subhuman (which, after all, they are) and after that, the main problem would be the bullet supply. People are perfectly capable of dehumanizing other people who are not dead, decaying, and trying to eat them, so I really don't see the problem, after everyone gets over the initial shock.
And any celebrity who wants to be a zombie on this show should have to agree to play themselves. Imagine how much fun they could have when the gang makes their way to what remains of Hollywood...
