I've always enjoyed PBS's Frontline series. For the US media in general, Frontline is first-rate & has good content. They are fair & researched too.
I watched the PBS-Frontline ep about the Washington DC schools & the high profile educator they got to run the programs.
I also remember a episode of NBC's hit drama; The West Wing doing a Frontline type documentary complete with the same VO guy.
Every 2nd matters.
