Most amateurish mixing (blending) of sounds in this film, never should the music and sfx overpower the dialogue!

and all I got was a lifetime of abuse from a bunch of non-combatants.

First--Music and sound effects should never be louder than voices. This is the kind of mistake an amateur filmmaker would make.Second--Subject was intriguing and tragic at the same time.
These children--through no fault of their own--were subjected to unspeakable horrors by their own government, citizens and even the mothers that gave birth to them. Compensation and an apology is long over due.Third--Freida (Abba member) --never realize the depths of her selfishness. First she abandons her own children to fulfill her musical dreams. Then she abandons her own people.
These kids of Norwegian mothers and German fathers are HER people. With all her fame she should have stepped up to the plate and yelled "NO MORE" and demanded justice.
She had the chance to tell her story and change the course of lives of so many people for the better. But instead of becoming the humanitarian, she became more concerned with her own reputation, money, and fame.

But I couldn't hear the narrators over the music.
You should never make the background music louder than the speakers. Ever.
It's "background" music for a reason.If you have amazing hearing, then this mini-film is the one for you. The subject is definitely interesting and captivating (from what I could hear).
Good luck.

pretty strange what hitler dreamed up...

Very provocative. This is the first time I've heard of this experiment. It's bizarre, to say the least, but then most of Hitler's nazi campaign was.
I don't recall my father ever telling me about this, though he shared many personal stories and books regarding nazi Germany and occupied countries. He was a soldier with the allied forces there. I don't think he ever got over horrors of it, God rest his soul
