If you allow me to put it on the fiction shelf or Philosophy, then it is a great production. I know Mormons believe it all literally, but there is another side to the story that can not be told by the movie maker without defeating the purpose of the movie. So here is my most friendly musing:
A great epic that unites a people. That's why Mormons can not be stopped. They have created their own identity with an epic story. As a people they have a history, a destiny (the elect), an exodus, a scripture even if it is Midrash, a Holy Land, a State and a High Priest and they are great at propaganda, diligence, education, general morals and adaptable. They also understand the power of certainty, identity and an imaginary reality. Their religion especially if understood as being of human origin is quite a remarkable success in having broken through the 5 Million Members Mark and is worth 40 Billion+
