Unfortunatley I dont think its back untill late next year, i maybe wrong but im sure i read that somewhere. im also fond of the zombie flicks/ post- apocolyptic. I gotta admit my fav at the moment is proberly the Dawn of the Dead remake.
Yeh I see what your saying, it is definently aimed at the people who are already fans of the genre.
I was a little disappointed with the storyline involving "the arm-less man" hopefully, like you said, there will be a decent story to come out of that. I just hope its got the legs to carry on for a few more seasons
