Frontline on PBS on Saudi-Iranian conflict

I watched one hour of the first episode.  Horrible.  He goes to Iran and tells viewers that there is suppression of political freedoms in Iran. He goes to Saudi Arabia and offers no such warning to viewers.  His main experts on the subject of the documentary are two: 1) a retired US diplomat who is a big fan of Saudi regime; 2) a Princeton Professor who is know for being very close to the Saudi regime and to Muhammad bin Salman.  After one hour, I learned about US documentaries what I knew not before.  He also adheres to Saudi regime talking point: that Saudi Arabia was a feminist democratic republic until 1979 when Iran revolution came and the rebellion in the Grand Mosque occurred. But what about the Jihadi rhetoric and religious fanaticism which was employed by Saudi regime against Nasser and against the Left in general BEFORE 1979???
