At over a decade old, this focuses on the techniques used by "spin doctors" to spread doubt and misinformation. Since this documentary was made, we have seen those same techniques used for covid, a proliferation of think tanks, and increasingly politicians in the US, the UK and my own home country (NZ). It's not a brilliant documentary, but well worth a watch in light of how much the world has changed since it was made. I'd recommend this

Having read Oreskes' book, the documentary felt too preachy and not very deep.
