Turning Point: L'arme nucléaire et la guerre froide

It gives you a wide view of history narrowing down to the modern day as to why things are the way they are, and how by learning from this we can we prevent catastrophes from happening in the future.

It's really important to watch it for us, as humanity, to understand our need for the ability to choose and speak freely, and how suppressing that freedom leads to dehumanization, excess patriotism, and personal selfish ambition.

If you do disagree with something while watching it that's respectable, but in the end the best perspective the documentary can teach you is the understanding that in the end peace and freedom of choice is what humanity wants and needs.

Really recommend it, and I usually don't review movies, but I can't stress it enough - watch it to the end. Because it helps you to form an educated opinion about the present day. And most importantly, how we can truly influence the future.
