Crusades: Would have been a "5" if not so much "down time" in scenes of soldiers marching in rain and desert. About 20% too much time. And, it had the dreaded scratch toward the last half hour.
Luther: Excellent 5-star. Includes his greatness, true doctrine of the Church (body of Christ), faith, grace. His warts are plainly visible as commentators discuss his views on peasants and Jews.
Islam: Pure propaganda. 3 hours of Islamic Facism with less than 5 minutes on Koran. Would lead a novice to believe that all that is good in the world was accomplished by Islam/Muslim. Creates the thought that Islam/Muslim is a geographic, political, economic entity; hardly a religion. If one knows nothing about the Ottoman Empire, this would be intestering.
David: Excellent review of empires that Israel/Judah faced: Assyrians, Bablylonians, Greece, Roman.
Peter/Paul: A little week on analysis, commentary, and detail. Nice overview.
