Very good series covering the factual aspects of the period in great detail. However it could have been so much better were it not for the shameless promotion of some pointless commentators.
Often, as is the style with most BBC documentaries, there is an annoying repetition of detail we have just witnessed. There is an assumption that the viewer has no memory. Pointless waste of film time and quite frankly demeaning. Also irritating is the laughable, and deeply insulting, speculation as to the innermost thoughts of the Nazis and victims involved.
Most of this is obvious fantasy extrapolation from events, however many of the commentators are amazingly contradictory despite this. The worst error however is boring, banal and unsupported commentary parading as knowledge.
Commentary from vacuous individuals purporting special knowledge gains zero out of ten, the quality of the "run of the mill" documentary makers ensure it is so much better than the headline flops.
