It’s about us. This is what I tell people every time I proselytize to the unconverted.
Consider me a missionary that goes out into the world and speaks the good news about good stories including The Walking Dead. When it comes to this particular conversion, I go to those who are “not into zombies”, “think zombies have been overdone”, and even those who “don’t really watch a lot of TV.”
The Walking Dead started as a graphic novel series, and is still going strong as that. If you prefer that medium, then I recommend it as much as I do the TV Series that came later. The two share a lot of things including characters, story lines, back stories.
