I chose to watch this due to the misleading description. It clearly states that Mr. Pollan will explain the natural history of four common plants and describe how these plants deftly manipulate human desires. While he does explain some of the history of these plants which I found enjoyable, he did not enter into any coherent discussion on how any of these plants deftly (quickly and skillfully) manipulate human desire, unless you count the less than two minute scientific explanation of how cannabis effects the human brain. Huh, no surprise there, I think he may have smoked too much of the stuff during the making of this 2 hour propaganda film. While I am all about saving the earth and stopping GMOs in my food, I do not see how they would have anything to do with the true botany of desire. This was just another ploy to trick people into watching a very biased and agenda filled film. This film (and probably the book too) has absolutely nothing to do with how plants manipulate human desire, however there was some manipulation going on, it just wasn’t coming from the plants. Don’t waste your time.
