I think I might just be bored with the prison. I'm a fanboy myself and I may be getting swayed in my view a bit from my wife who was over it a 1/4 way through last season.

Some of the stuff they are doing is just stupid I think and that may be where they are losing me. I do like Carol's character but I wasn't surprised it was her that killed the 2... or well we've been led to assume she killed them. I presume they were dead and she burned them before they could turn. Exactly as she should do. The rest are acting dumb about it. I guess I just want it to be a tad less soap opera and a bit more gritty like it was the first season. But I guess I can see how they have to develop the characters more before they make a huge plot shift and they leave the prison.

I too fear Hershel is the next to go, as he is one of my favorite characters.

I agree with another poster that I think it was one of those girls feeding the walkers. She was naming them so it makes sense that she fed them.

edit: I just remembered the scene where they showed the horde of walkers... I'll be patient.
