I like the show for what it is, a cheesy zombie show. The thing that bugged me, and I don't know if it was lazy writing or lazy prop guys, is the scene where they show the prize for the shooting contest. 10k asks "is that an M82 Barrett?" It's not. It's an EDM Arms M96. All the other stuff I can take in stride, suspension of disbelief and all that. But getting the gun wrong for no reason bugs me.
