I caught a bit of this last night. Really enjoyed it - W was watching as well and he was intrigued by the emotions - that's a big one for us.
What I really really liked - is that one of the teen girls said that they didn't want to live a non-monogamous life. It was all she'd ever known - but she wanted one man, one woman.
I loved that the parents said that it was her choice, and they will love her and support her regardless.
Overall - while I don't watch reality shows - it was one that caught my interest.
