... Evil? Zombies?

No no no no, not at all. They're not evil. Sure, by our standards what they do is bad, but so are many of the things that animals do. It's survival, not evil. Their killing us is no more evil than us killing them. People only view it as evil because they're in survival situations.

The story of it makes that point even more clear, which is especially good because a lot of the casual zombie fans will only be familiar with the idea of eradicating all zombies for human survival. They need the view really shoved in their face to understand the theme can be so much more than mindless gore.
