Sat through this entire 3-4 hours BBC documentary with 3D graphics to fully understand " the holocaust " horror . This masterpiece of fact compilation that is absolutely neutral , goes into every angle of subject visualization and authenticity has changed me forever . A must see for everyone to understand how thin are the lines that we draw , how delicate is the balance of peace and most importantly how the most intelligent , cultured humans can metamorphose to utter cruel worthless beasts , so that never ever something like this can happen here again !!!Amazing narratives , real photographs and visualization .Children should see this , do not prevent them from seeing the truth by raising some rating standards !!!
