When I was in grad school, a professor of mine quipped, "Just because a paper is published in Nature (the most prestigious and impactful journal in at least the biological sciences if not all hard sciences) doesn't necessarily mean that it is wrong." We then proceeded to eviscerate a high profile Nature paper that was utter crap. It was an important lesson, but it is also one easy to get wrong. Claims in the most reliable of publications can be wrong, and claims in poor publications can be just fine. If the source is in dispute, there isn't really a substitute for digging in.
In your case, citing a documentary film isn't necessarily bad per se, but video citations are an extremely inefficient way to cite a fact when a text quotation of a reliable source would do. Also, secondary publications, like documentaries, are always less reliable than the primary source material from which they are drawn, but if the secondary source is good at citing its primary sources, it could be really good. Secondary sources are valuable to the extent that they summarize, compile, and make available the primary material. This is why Wikipedia is so great. It isn't always right or complete, but it almost always links to primary material so people can evaluate the summary and dig into the primary. Documentaries don't do this very well.
Bottom line, it is probably pretty easy to cite a source that is easier for your readers to consume and assess than any video, unless the video is like a demonstration of something. On the flip side, charlatans love to cite videos, because they are extremely inefficient to attack, as they take time and effort to quote, and the population of people that bother to watch more than a little is strongly enriched for people who believe the conclusion, because skeptics will give up long before they get very deep.
