Whatever you may think about J. Edgar Hoover, he brought science into criminal investigations; establishing the first national fingerprint registry, and creating a forensics laboratory at the FBI.
I was hoping this film reveals the the motivations behind the real-life J. Edgar Hoover's ruthless and Machiavellian methods. Hoping it could explain how he could justify subverting the law he was pledged to protect. He created an "us versus them" atmosphere in public life that persists to this day.
He has a domineering mother, and is constantly trying to prove himself to her. He represses his sexuality, and like many politicians today that are guilty of the same behavior, he constantly seeks deviance in others. And, like most public figures, he suffers from insecurity that causes him to constantly seek public attention.
He was not a nice person, but he did bring professionalism to the FBI.
It was an interesting biopic, but it left you wanting to know more.
