I just finished watching the last episode of season 2.
The whole thing had become utterly preposterous and I see that this whole Whiny Thread is justified!
It's been slightly redeemed by Rick eventually
killing Shane, and Dale who had become such a ridiculous mother hen figure also dying. The samurai with the amputee zombies looks fun too.
But really the whole season 2 has no foundation at all - the first thing you'd do is use the abundant maps everywhere to find fortifications, improve and barricade them, build walls, make organised contingency plans, set up an organised decision process. They just lurched about from one crisis to another and it got very tedious.
As has been said, the farm being "protected" by some sticky mud was utterly ridiculous. They had an idyllic place to live a great life - they just needed to put up 15 foot walls, get organised and have better characters. Shane, Rick, Dale and Hershel were just all far too extreme too.
I did laugh out loud in episodes 11 to 13 though, when Carl kept popping up out of nowhere, in the middle of the night, in the middle of dangerous woods, at the top of a barn... wearing his gay little cowboy hat
