History Discussion ASAP

We have discussed a lot about religion in this course.  Christianity went through a tremendous amount of changes in America (new churches, different churches, etc.).  One faith that came on the scene during the era of the Second Great Awakening was Mormonism.  This is talked about a lot now because of people like Mitt Romney and Glenn Beck. The Mormon Church is also one of the most wealthy organizations in America today.  We cannot ignore the history here.  Is this a legitimate Christian movement?  If not, what is it?  Why do you think this?  Why do you think hundreds of thousands of people flocked to it during this period of time? What do you know about Joseph Smith? Brigham Young? (125 Words)

Here is a PBS documentary about Mormons:
