I think the show has jumped the shark. The story hasn't progressed since they bought the farm a season ago and it continues to get progressively worse with every episode. At the very least by now:
1) the farm should have been heavily armed, stocked and fortified
2) they should be openly broadcasting to attract every survivor within listening range
3) they should be culling the local zombie population 24/7
4) They should have incorporated a full trama center
5) They should be operating armored vehicles and collecting fuel and water transports to increase range and mobility
Let me add that by now I would have collected the severed functional zombie heads of the entire CNN on air cast and mounted them on my wall as real talking heads (a "live" art display?). Hey, you are all free to pick your own favorite theme; ex-bosses, ex-girlfrends, lawyers, politicians, traffic cops, inlaws......you get the idea. In short the show needs to loosen up and have some fun exploring the whole zombie genre. Lately, there has been too much soap and way too much stupid.
