I finally got through this series and came away with the knowledge that personal integrity was not high on the list of features that these six individuals possessed. However, determination, greed, selfishness and an exaggerated sense of self, along with the lack of respect for others is quite prominent in all of these criminals. Also, one or two of them was a nitwit, but so are a lot of people who have attained positions of power, just fool people, tell them what they want to hear and who to blame, it's easy.
From the beginning, due to the narration, I knew is was "tongue in cheek" " satirical" "sarcastic" etc. It was the tone and delivery of the narration that kept me watching, despite getting bored with the Frank Lucas and Whitey Bulger episodes. I didn't know who the narrator was since I rarely look at the credits before a movie or episode of what I'm watching, so once I discovered who it was, I had to Google Peter Dinklage. Now I know that he was in "Game of Thrones," which I didn't watch (not interested) and "The Station Agent" which I'll look up. Finally, I realized he was in "Three Billboards etc..."
This entire series struck me as entertainment, not to be taken seriously, just enjoyed it for what it was. What does it matter if it's not completely factual, what movie is these days?
