Don't you just love shows like this? I mean this one is complete and total bunk. Well, OK, it's not total bunk, it's more like mostly bunk. Some of it actually works. The problem is that the key points are pure speculation and conjuncture with little hard evidence to actually back it up. But to be fair, there is almost as little physical evidence to back up the current working theory. So it's really a matter of the leaps it takes. But, there is more evidence for the official theory. Ultimately though, who cares, it feels like "In Search Of," it feels like "The X-Files," it feels like "Ancient Aliens," in other words, it's entertaining conjuncture and speculation, but that works for pure entertainment.
