We get a glimpse of important history with this film. Of course we might be missing pieces to better understand Hoover but the essence is there. I am glad I did not pay attention to the professional critics who look at films different most times that us regular movie fans. Acting was terrific on multiple fronts and you had a good basis to judge Hoover from past understandings and now the film. Basically Hoover did a lot of good but he was also the kind of guy you would like to see shot......it did not have any rules and history shows he manipulated powerful men. I am went to Must Go because of the importance of Hoover to the US.
