In recent years Frontline has severely damaged it's credibility due to it's evident left leaning bias. In a country (USA) so divided politically on every issue, viewers should be skeptical when they watch documentaries where every interview subject agrees, and there's no contention that reflects nation's divide on these complex issues that we deal with. Watching Frontline in 2023, someone who doesn't know any better would imagine the US as a nation united on these issues, because Frontline crafts their narrative by using viewpoints on only the left side of the debate. Because of that it would not be an exaggeration to label Frontline documentaries in 2023 as political propaganda.
