Ok, really, what is with the History Channel's insistence on continuing this absurd show? I was shocked when I noticed that this show is actually in its 4th season....WHY! How can a show thats managed to determine that EVERYTHING that ever happened in human history is the result of aliens, keep getting made? I was willing to play along with the original documentary but the fact that its still going is kind of worrying. If this show were airing on SyFy I would not bat an eye. However, since it airs on History, the fact that this show might be popular enough to warrant making ever sillier episodes is quite alarming. Are there people out there watching and believing this crap?
