"They asked me to do a couple of episodes of 'The Walking Dead' but I didn't want to be a part of it," Romero told The Big Issue. “Basically it's just a soap opera with a zombie occasionally. I always used the zombie as a character for satire or a political criticism and I find that missing in what’s happening now."
In 2011, Romero said he loves "The Walking Dead" comics, but hadn't seen any of the episodes at the time. "Listen I love Frank [Darabont], I know he's done a good job. I love the books, I never watched any of the episodes because… my zombies are sort of my own. I didn't want to be part of it. Producers called and said, 'do you want to direct some of these,' and I said no. Because I just didn't think it was me," he told io9.
I can't say I disagree with George here. I know the 'soap opera' aspect is what makes the show appealing to many of its fans, but for me personally, I prefer my zombie stories to be under two hours. To each their own.
