"Walking Dead" tells their writers to take a walk

In a surprising move acclaimed director and driving force behind hit AMC show The Walking Dead has informed his writing staff that they would not be brought back. The show that my wife and I have enjoyed as a suitable replacement for the lost favorite that was Jericho was picked up for a thirteen episode second season. Frank Darabont has said that he wishes to leave the old writers in the dust and go with a different format, possibly entertaining a freelance staff to write individual episodes. Which leads me to believe that the discussions my wife and I had about how the great plot and character development that kind of fizzled out in the last couple episodes was occurring elsewhere too. I think the public fan forums are probably an insight into the decision to move to different writing talents. What do you think? Have you watched the show at all? Did you get the last couple episodes back and forth emotions especially the Sheriff's wife?
