Great documentary. Some of the comments are acting like there are bad actors in every faith and this film unfairly focuses on a few within this community and all are free to go. This simply isn't true.
Most of the women in this community are not allowed to even receive an education. If they divorce their husbands, what we see in the rest of American society does not exist in this one; the husbands almost always win custody of the children. Why? Because judges will take custody from mom because leaving the "faith" is too much of a change for the child.
So can women leave? Sure, they can. But they have no education, no money, no skills, they lose their children, and their entire family turns their back on them. It is better to just be held down and have your head shaved, a wig placed on top, and do what you're told than leave. I don't think most understand the type of control that is in play here and not just on those in the faith, but of large geographic areas of a society where different laws exist.
The community found in this documentary is not small, is not rare, and has a lot of power and say not only within the localities they inhabit but on society as well.
