Yeah it's really well done for a zombie show. I know some people don't like the focus on character development over action but I think that's what makes it stand apart from the sea of zombie media and it keeps you interested. Like that damn cliffhanger from this most recent episode. I actually threw my hands up and said "WHAT!?" I hate waiting for a resolution but I get why they did it, no one wants to miss the next episode now.
Btw I think Johnny Cash songs can make anything seem more dramatic. They did it awesomely in Dawn of the Dead and it works just as well in this show.
