As a non-Mormon living in Mormon Country (Utah, USA) I was anxious to see this PBS program when it first aired last year. I have been married to a Mormon lady for the past 37 years and during that time I have had much contact with the church and have learned much about the faith and its people, although for personal reasons I have decided the faith is not for me. This documentary holds true to what I have learned about this most unique of American religious denominations. It is a fair-minded HISTORY of the Mormon Church and its wonderful people. It does not, however, delve into church doctrine or dogma. If you are interested in learning only about doctrine, this documentary is not for you. It would behoove you to contact your local LDS missionaries or the Church in Salt Lake City itself. They will be more than happy to cater to your curiosities, I'm sure.
One of the most insightful moments in the documentary is when the narration proposes an explanation as to why the Mormons are so centered upon the temple rites of sealing your spouse and your children to yourself for "all time and eternity". To paraphrase, "The church was organized in America during a time of great westward migration and family separation. It was a period in our history when children would leave home to seek their fortunes and never be heard from by their families again. The temple endowments were aimed at keeping the family together, if not in this life, then in the next 'for all time and eternity.'" This goes a long way in explaining why the Mormons think the way they do, and why the Church is organized the way it is.
I heartily recommend this documentary for anyone who is interested in American History and the history of the the Mormon people. It is one of the best, if not THE best, films on the Mormons I have had the pleasure to watch and own.
