Well, I am sure parts of this series are factual, but it is difficult to determine "facts" from fallacy and questionable interpretations.. A good deal of this information has never been conclusively documented, for the simple reason that it was criminal behavior, consequently never recorded or documented. Regrettably, filmmakers rarely let the truth get in the way of a good "story".
Not sure why they have actors giving interpretations, when there knowledge of history is limited to the script in front of them. I do appreciate the actual historians giving input. but am left to wonder how much of their understanding was edited. Immense societal factors such as the Great Depression, World wars, racism and class struggle were completely ignored.
And the descendant of Capone describing him as being motivated for "family", rather than ego, greed and being predisposed to murderous psychopathy is bizarre. Granted it is her balloon, but any attempt to portray these people as a misunderstood product of the times is nonsense. They were psychopathic criminals.
