Okay, I picked this up because I am a huge fan of the TV show, and because it's been years since I read a graphic novel. I was pleased to discover that this is as good as the TV show (although it's hard to compare the two as the TV show diverges somewhat from the course of this book). This might sound weird, but I loved Robert Kirkman's introduction - it turns out that he loves zombie movies for the same reason as I do: not just for the blood, gore and the sheer terror (although those things are good too, as long as they're behind a screen), but for what they teach us about human behaviour. What would we do if there was no government (not as appealing as it might sound), no rules, no laws, no norms for us to follow? Would we still follow them anyway, or would we set the clock back millions of years and start over? How would we cope without everything we've come to take for granted? These questions, for me, are what The Walking Dead is really about. I will definitely seek out the next one in the series. 
 Oh, and graphic novel Rick Grimes is much hotter than TV show Rick Grimes (sorry, Andrew Lincoln).
