The World War 1 episodes might be slightly more enjoyable, because I think those deal a bit more with "history" in the sense of events and blow-by-blow of what happened. But it may be that Dan Carlin's stuff just isn't your style. Carlin's approach tends to be more of a discussion where he uses the backdrop of a historical event to ponder some aspect of the human condition. There is also a lot of repetition and redundancy and rambling when he talks, so some of the appeal is people who just plain like the sound of Carlin's voice and enjoy hearing someone talk about something interesting. I tend to divide up my podcasts into mental categories of "those I listen to at normal speed" and "those I listen to at 1.5x or 2x speed." Carlin's stuff fits into the first category for me.

Are there other history podcasts you've enjoyed? I think something like The History of Rome might be more of your style.
