Well......had the opportunity at a more effective ending...(SPOILER)....
Well, for a dramatization of a known person, this limited series wasn't the best but it was far from the worst.
My thoughts are a much more emotional and effective ending would have been to dramatize her death instead of having her on a beach reminiscing about her dead sons. To me, that sort of ending lacked what could have been a more intense ending and a brutal end to her life would have been more shocking. One of the reasons I think it would have been more intense is because in ways the series sort of sympathized Blanco and many viewers most likely have a positive opinion of Sofia Vergara, which would have added to that depiction.
I just read some more about Griselda Blanco and wow. Talk about a whitewashing on her brutality by Netflix. Her friendship with Marta (the woman who introduces her to crack and later dies of an OD head injury after falling through a glass table). In real life, Griselda and her loony hitman tortured the woman, even pulling her finger nails out over owed money, with the woman dying.
I guess the creators didn't want to create a factually based Griselda to erradicate affection toward their fictionalized creation.
