I have mixed feelings on this... I haven't seen the show because I don't think that we have it on our satellite (we only have basic, with a few extra channels) but I'm pretty sure that my dad has watched it.
I watched and loved Big Love for all the seasons except the last, I would go over to my parents house and spend the night on Sundays and we'd have a big dinner and then watch the show. It was interesting and entertaining. I know that there is a huge difference because Big Love is fictional and Sister Wives is not, but I do think that Big Love kind of brought Polygamy back into the spotlight and maybe made it easier for the family on Sister Wives to expose their lifestyle to the rigors of a reality television show.
I think that reality shows like this, and Little People, Big World, etc are good in a sense that they show us how different types of people can lead relatively normal lives (during the first season or two, then they start bringing in the money from the show and it all changes, but that's a different subject).
Most of the time, all we hear about are the bad things about Polygamy - the cults, the young wives, murders, etc. It's like anything, if you only hear about the bad and aren't exposed to the "good" (I use that term loosely) then how are you going to learn about how things really are there?
Don't get me wrong, I'm not saying that I support polygamy or anything like that. I do believe that people have a right to live how they would like to - whether it is with 5 wives or something else, as long as all are informed on it and it isn't negatively affecting anyone else. The problem with most polygamists, that we know about, is the cult type situations that we hear about - children aren't give a choice and are married off young, women are misinformed, brainwashing, etc.
On another subject that's kind of on the same topic - I have a couple of really good friends that are into alternative lifestyles. A few of them are married, but also have girlfriends. Their wives know about it and seem to be alright with it, there are entire underground clubs and bars just for this particular type of lifestyle. They hold meet ups at local bars as well, usually under some other name and are pretty discrete about the whole thing. The men, and women, are mostly highly educated and smart people. It's unfortunate that they have to keep this part of themselves hidden because of the public perception on the lifestyle and polygamy. Maybe these shows will be able to better inform the general public. Only time will tell for sure.
I'd be interested in watching the show, maybe I can get Mike to download it for me.
