It was certainly worthwhile and fascinating, especially if you are largely unfamiliar with Luther. I am pretty familiar with the period, but still found much insight and much to think about.
It was refreshing that Cardinal Dolan was featured on the program and his honesty about the corruption in his own church at the time was refreshing. As the program spoke more about the developing reformation, it would have been nice to hear a little more from the Catholic perspective. That said, it amazing how many of Luther's reforms have found their way into the Catholic Church (local language Mass, local language Bibles, better educated clergy, better educated laity, taking on corruption, etc.). It was Pope Benedict, as a Cardinal in the 70s, that mentioned that the Augsburg Confession could possibly be seen as a Catholic statement of faith. Obviously that hasn't happened, but it is incredible just how much things have changed!
I guess my biggest hope and takeaway is that protestants watching dig deeper into Luther's writings and into Lutheran belief, with the hope that they discover the Sacraments and liturgical worship. If Luther were alive today, I imagine much of his time would be spent trying to reform today's protestant churches!
