From my own experience with zombie culture, zombies really aren't that easy to kill.

I think this is a good metaphor for life; what do you do when your time is almost up, when you're on the run for your life and your days are numbered? Zombie culture gets us thinking about what we'd actually want to do with our last days, and the sacrifices we would or would not make to survive or help other survive.

I don't think it's accurate to say that if you dig zombies you 'dig the entire zombie concept.' This writer seems to lump all forms of zombie culture together on one united platter, but I've read and watched a variety of material that has provoked extremely different reactions and thoughts with me; if anything, it makes me less interested in zombies, and more interested in the human condition and the way our civilizations struggle to stay together during an apocalypse.
