His overall body of work stands up and speaks for itself. But he misses the mark, tragically, in this. He seems to be very interested in Hoover's homosexuality, and there are intensely dramatic scenes involving the protagonist and his lover, Clyde Tolson. But the implicit involvement in conspiracies and cover-ups in the assassination of JFK, RFK and MLK (to say nothing of Malcolm X) are not dealt with at all. Hoover practically had the Warren Commission as his captive audience in the presentation of evidence, resulting in one of the greatest travesties of justice in American history. The film does briefly deal with the blackmailing of MLK, but it is not developed.
