IGN: Okay, so I don't like to use the term "filler" with regards to The Walking Dead. Breather, maybe. Comedown chapters. Time for characters to reflect on shock and tragedy. It's the way this show works. It's what this story demands. The Walking Dead, like the comic series it's based on, is a story without any clear endgame. It's about just living in a terrible effed-up world and finding specific reasons to carry on and not stick a pistol on your mouth. And, as much as some bitch about slower, character-driven episodes, the reason this series is such a huge hit is that it appeals to large amounts of people who'd never in a million years watch a zombie horror movie or show. Because it is, in fact, all about the characters.
