Such is the fundamental question of AMC's widely successful show "The Walking Dead," which returns this Sunday for its second season.
Based on Robert Kirkman's comic book, the series is one of the more odd yet complex dramas on television today. At its core, it's about survival and the psychological stress that spending every waking moment together has on a small group. But that could be said about all human beings in that surviving the world is something we do on a daily basis; the trick with "The Walking Dead" is that a pack of ravenous zombies could be lurking around the corner, ready to make you into dinner.
Viewers are consistently presented with questions of morality, instinct and terror, where plots are less about discovery -- there's no race for the cure -- and more about the struggle to exist.
CNN checked in with "The Walking Dead" showrunner/executive producer Glen Mazzara to see what's in store for season two, how the show finds its storytelling voice and just how they get that authentic zombie feel.
CNN: On average, how much are you thinking about zombies each day?
Mazzara: All of them. I wake up thinking about zombies. How do I keep them scary? What's new, what's different, what's fun that we can do with zombies?
CNN: How did this show become so popular on just a six-episode first season? What's the appeal?
Mazzara: It's visceral. There's an immediacy for anyone watching it, where they think, "what would I do?"
People buy into the idea that a plague could wipe out things. We've seen that, and it's in the zeitgeist now. It's playing on the everyman level where it's about the survivors and not about what happened to the collapse of government or infrastructure. You get in the car, and it runs out of gas, and then what? Meanwhile, you're being chased by zombies.
CNN: Remember the swine flu? That was a legit panic.
Mazzara: Yeah. It's like when you're watching a horror movie and the people move into a haunted house. And you're wondering, why didn't think just move out? Everything our survivors are doing, hopefully, strikes people as realistic. They're making decisions that ordinary people would make. And none of those decisions have very good consequences.
CNN: There's also weird psychological dynamics between the characters where they have to get along while also ensuring that they survive, they want to survive, and everyone around them survives too, because as far as they know, they're it.
