I thought this did an excellent job, and was visually compelling. While many critics are quick to note how it glosses over many of the complicated aspects of how the West was explored, colonized, its people driven and killed, and game exploited, they seem to forget it is ONLY FORTY MINUTES LONG! I was actually amazed at the variety that WAS included, far more than I expected. I am not going to be nit-picketty about what I would have preferred to be included.
To Connie S. The Mormons who helped discover Gold were not there because they were tired of their faith and felt brainwashed, They stayed there because they had come to California with the Mormon Battalion and needed to earn money they could take home to Utah with them. Nearly all of them returned to Utah within a few years. That sure doesn't sound like they were disillusioned with their Mormon faith to me. Sounds like somebody needs to do some history homework.
As to knocking it because it gives a feel-good approach to this subject. I would rather see this than a documentary that focuses ENTIRELY upon the deprivations and slaughter of the natives, the buffalo, and the "evils" of Manifest Destiny. This version of events is just one perspective of MANY. Let it be what it is, there are plenty of sources for perspectives of the Indians, etc. Not hard to find.
