Things this movie got wrong.
1. In the movie, the FBI are portrayed as the "bitch" agency staffed by naive incompetents, while the CIA/DoD are portrayed as the "big boys." In reality, the FBI helped get their favored candidate (Trump) elected, while the DoD was silent and the CIA got made fun of by the president-elect.
2. In the movie, ultimate power is portrayed as being in the hands of "people who are elected, not appointed." In reality, the head of FBI disobeyed his superiors and just did whatever he wanted. The appointed people got the upper hand on the elected people.
Pretty minor points seemingly, but given the "depth" and "reality" this movie purports to, not really.
