I have watched the First and Second Seasons. Third season is not yet available to me for viewing.
When the first season was aired I was actually hooked on to it. The fist season was shown continuously from morning to evening when it concluded. It was quite thrilling.
The episodes are well documented and presented.
However my basic doubt is that after the end of WW2 if the US had such valuable information on the possible whereabouts of Adolf Hitler a most prized catch and probably some high ranking Nazi's too what stopped the US and allies from pursuing the matter and making this most sensational arrest.
That basic question I feel remains unanswered.
