Like the rest of you- I was fascinated with how this series accurately portrayed cult life, group think, leader worship, the corrupting affect of power, etc, etc.
I was confused on where it came down on polygamy though. There were several and often- digs against the whole lifestyle (lack of empowerment of women, jealousy problems, money issues, etc) but the last couple of episodes almost made the case for the state not regulating poly-amorous relationships. "Let people love who they want, how they want" seemed to be a message that was lurking in the script. But that message was hard to reconcile with the damage that the lifestyle did to those who participated.
