I listened to the French revolution twice, it was that good.

They are all very good. Even with a decent background in history, as an American, I tended to think of the 1840s in terms of the lead up to the US Civil War and ignored/forgot most of what was happening in Europe at the time. The season he did around this period was a great reminder of all of the seeds of change and destruction for future generations that were sown in this decade.
