Loved the topic but don't be fooled by the clear bias that just gets stronger and stronger with this movie. (Opinions are like derrieres, everyone has one) but to present this as a documentary and not own the fact that it promotes certain things and dismisses others is to lower it's credibility.
Here's my bias: Liberty is a moral imperative. -and it's not for the government to decide for people what will or will not make them happy because eventually, they will use their power to impose it on everyone. This is what is so wrong with Marxism, Socialism et al. The collective notion that if it's good for one person, it must be good for all. (That's a lie too, because it's usually only good for the people who are trying to subjugate and enslave others.)
It takes a while for this movie to show it's bias but show it, it does: Religion, bad. Communes, good. And many more. For any film to ignore the matter of free will, individual choice and the ability to make those personal decisions about what one choosed to pursue and how he will spend his time, is to ignore an essential quality for happiness.
Not that part of this film weren't moving. The woman who surmounted getting run over by a car was incredibly moving, but the ingredients for happiness are not the same for everyone, yet this film has a collectivist bias. Being free enough to discover what is important in one's life is part of the joy of living. This movie may either intentionally or unintentionally promote the notion that the recipe is the same for everyone. Just do as I say!
