Thanks for that link, it's pretty interesting.
I'm not surprised that the more "boring" relationships (because they were drama-free or not "weird" or complicated enough) were dropped from the documentary, or that it was edited to make it look a certain way. This usually happen in documentaries since they care about ratings and want to make it sound all exciting, but they also don't want to be called immoral or anything so they do state their opinion in "the status quo is better" as much as they can.
I'm still curious to see it as I'm relatively new to polyamory, and new as far as actually living it. I'll just remember to take everything with a pound of salt, as usual in this kind of things.
