It wasn't much of an advert for polyamory was it.
All the groups had unhappy people in them.
The younger people were just doing the hippy free love thing. Nothing new really and will probably grow out of it.
The older people seemed to be desperate to hold on to their marriges regardless of the fact they no longer made each other happy.
The geeky people just seemed happy they found a woman that would get with them.
Non of them managed to sell it as, happy concenting adults sharing a loving bond, as the poly community often try to position it. It was more selfish people taking advantage of insecure partners.
