I’ve watched Apocalypse WW1 in the past (there aren’t too many decent documentary series on the topic) and I can’t remember how highly I rated it. Certainly not high enough to have it stick in my mind.
This one is boss though.

Originally aired in 2003, narrated by Kenneth Branagh. They do use some of the footage more than once across the six hours, but it’s time well spent. Only six episodes but one on the Naval battles, one on the aerial battles, etc.
Certainly better than any of the array of ‘WW II in Colour’ series that are out there, which can’t hold a candle to The World at War.
