Well, if the Cosmos series is clearly made with the intention to teach and educate, Ancient Apocalypse is meant to sensationalize and somehow shock you. Literally EVERY sentence in the series is accompanied by some cheap, dramatizing and sensationalizing sound effect. A stab, a hit, a deep bass rumbling for effect, it gets highly annoying. And it's a shame because the chosen subjects are truly amazing and have enough consistency to carry their own weight through the series. I "met" Graham Hancock on the Joe Rogan podcast and every time he was there he made a very serious impression, I regret he had to make Ancient Apocalypse this way and on Netflix. Even the title sounds like (and is!) clickbait. If you can filter all this out, you're in for a historical gem.
