I always find Giorgio Tsoukalos funny. That man is always so enthusiastic and sure of himself, even though he spouts the most nonsense. Nonsense that I like to hear and see. Whether I believe it all is another matter, but I enjoy looking at these theories. And sometimes there really seems to be something in it. When I look at the episode descriptions, there is indeed little new in it. But I'll still check if I can watch this somewhere. Giorgio is now so famous that he even had a cameo as himself in Resident Alien. That was very funny.
If you have a VPN you can watch it on Prime Video, Roku and I think also on History. In the Netherlands, I certainly couldn't find anything. Good luck, it's really nice with Giorgio, you describe him well. ;)
