When you run a show like this, you never know who you'll talk to when you open up your instant messenger during the program.  During Monday's show I had the opportunity to talk to a person who said he was part of the production staff of the show "The Walking Dead".  AMC scored a hit with this comic book adaptation.  On the Halloween premiere, it drew 5.3 million viewers, a new cable TV record, and last Sunday's second episode attracted an audience of 4.7 million, a never-before seen retention rate on cable.  In view of that, AMC has renewed the show for a second season of 13 episodes.  The gentleman I spoke with used the right name, but I of course have no way to know if he was the actual person he claimed to be, and he asked me not to use his name.  The interesting comment he made during our conversation was that "The Walking Dead" actually has other implications than the mere takeover by zombie hordes.  He said that the hidden meaning to the program is actually deeply rooted in one of America's current social problems.  The show, he continued, is actually an allegory of our trouble with illegal immigration.  The zombies, he claims, are actually the equivalent of illegal immigrants, who started out in small numbers and have exploded exponentially in growth as legal residents who protest their being here have been kept in check by legal maneuvers and lawyers willing to twist the law to make a buck.  The parallel is actually shockingly similar indeed.  Just like the "Walking Dead" zombies, illegal immigrants are slowly taking over, and now we have entire cities where you can go and never hear a word of English since it's easier for legal residents to just give up and let the illegals have the territory because our government refuses to back up its own laws.  In the end, if we don't clamp down and force out illegal aliens, they will succeed in making our land theirs, and the legal residents will basically be homeless in their home land.  The parallel to the show and this hot-button issue, claims my source, is what is making "The Walking Dead" such a popular show.  I must admit that I never considered this when the show went on the air, but now I can see his point.
