Adam Curtis is great. I recommend even looking into his older material, such as The Mayfair Set (won a BAFTA Award in 2000). Another older documentary of his that I recommend is The Way of All Flesh (1997) which is a rather remarkable story on HeLa cells with a depth I hadn't encountered before. To give you an idea of the subject matter, here's a quote from Wikipedia: "HeLa cell contamination has become a pervasive worldwide problem – affecting even the laboratories of many notable physicians, scientists, and researchers, including Jonas Salk. The HeLa contamination problem also contributed to Cold War tensions. The USSR and the USA had begun to cooperate in the war on cancer launched by President Richard Nixon, only to find that the exchanged cells were contaminated by HeLa." Some of his material is viewabled on BBC iPlayer if you have access to that. His older material can be challenging to find. You can download his complete collection via torrents.
