Vampires were so 2009. For better or worse, America's flirtation with zombies has burst into a full-blown obsession with the reanimated dead. AMC's "The Walking Dead" is the year's water-cooler show of choice (at least around the Times office) and no fewer than 70 full-length zombie flicks of varying legitimacy were released over the year. In-depth zombie debates left the comic book stores and became de rigeurrghrhgrrr. Arkansas certainly wasn't immune to the fervor. The sadly deceased walked along downtown for the Little Rock Zombie Walk in October and UCA writing professor Robin Becker released "Brains: A Zombie Memoir," a well-received new addition to the zombie lit canon through HarperCollins Publishers.
