A very mixed bag documentary, supposedly it brings together several scientists from very different fields, though these fields are primarily the cutting edge of human consciousness, miscroscopic life and deep space research, yes a lot of excitement about space and half the scientists are female, which is just silly feminist promotion, equally, not every scientist is equally articulate. So when you watch a fairly long documentary, you at least want a subject well explored, or at least to get a lot of deep insight from it and that is where this documentary fails, its a wonderful character sketch, we do get a bang for our buck, but the way it skips from one field to another, sometimes with scientists who are no doubt good in their field, but unable to express it in a meaningful way, you leave kinda disappointed.
