DOCUMENTARY SERIES PREMIERE: On March 16, 1968, Robert F. Kennedy announced his candidacy for President of the United States, throwing his hat into the ring quite late, in an election year, in order to provide policy alternatives to incumbent Democratic President Lyndon Baines Johnson. It’s not precisely 50 years later (Netflix missed that opportunity by more than a month), but today, Netflix premieres a four-part documentary that’s about much more than Bobby Kennedy’s presidential aspirations. This nonfiction series begins with his brother, President John F. Kennedy, and traces Bobby’s personal and political life as he weaved in and out of the orbits of McCarthyism, the White House (as his brother’s Attorney General), civil rights, the Cuban Missile Crisis, and anti-poverty and anti-war campaigns.
