I don't need zombie action all the time, I like good characterization and talky scenes but the Walking Dead doesn't offer that most of the time.
My favorite scenes of sundays third season premiere of Game of Thrones are people sitting at tables and talking to each other, almost the entire episode consisted of people sitting, standing or walking and talking to each other and it was awesome from start to finish.
Yeah, but to be fair the characters in Walking Dead aren't a bunch of politicians, lords, and noblemen jockeying for power and hatching elaborate plots against each other.
They're just a bunch of normal, everyday people who are trying to survive day by day, and who have the kind of simple and mundane conversations that real people probably WOULD have in that situation.
Personally, I think the show captures that feeling really well.
