Re: An awful lot of Dr Zaius maniacs in today.
"a lot of the most successful Sci-Fi series and stories have the Ancient Alien element in there somewhere. BattleStar Galactica and Stargate being the more famous examples."
Although I'm sure you know this, it's worth pointing out that most of those SciFi ideas not only re-date the TV show Ancient Aliens, but they drew their ideas from much earlier "aliens are among us", "aliens have visited us in the past" popularised by Erich Von Daniken (who is Georgio's mentor and makes the odd appearance on the show every now and then). And not forgetting the influence of Charles Berlitz and Lyall Watson's books too.
