To be upfront I have not seen The Talking Dead and all this is based on commercials shown during The Walking Dead.
A post show is something you do after a sporting event or after a season of a cable based reality show competition like a Top Chef or Project Runway not after every episode of a cable series. I like The Walking Dead but does it really need a post show analysis after every episode? The show seems pretty straight-forward with very little subtext. It would be one thing if it was a heady drama like Breaking Bad, Boardwalk Empire, or Homeland. Hell even the other popular cable horror series American Horror Story: Asylum is more deserving of the post show treatment because of how fucking batshit insane it is. Seriously you got alien abductions, demon possession, Nazi-like human experiments, zombie creatures, and the season has just started. It makes the first "season" look like they spent all their time on a boring ass farm in comparison.
