If you started Revolutions from the beginning and gave up, maybe give it another try with a later episode. IMO the first series, on the English civil war, is the weakest one I’ve listened to.
By the way, my favorite Hardcore History series was Wrath of the Khans, and I can heartily recommend it to anyone who hasn't tasted Hardcore History before. Last time I looked it was still free on his site, so get it while you still can.
On the other hand I really didn't enjoy the Dan Carlin episodes about WW1. His overly dramatic and histrionic delivery becomes tiresome. After about twelve hours of scenery chewing about how awful trench warfare was and all the grisly suffering, I decided he was enjoying it too much and gave up.
