Cape Spin is an extraordinary documentary about two threats to the survival of all species, including ours. On the one hand, it's about the crucial fight to find alternatives to fossil fuels—in this case, wind power, which just might help us save the Earth from fatal warming, toxic oceans and ground water, and the other poison fruits of oil-and-gas dependency.
And yet Cape Spin is also a brilliant study of another, subtler kind of pollution, which is every bit as dangerous as all the evils that it urges on us: propaganda. The war between those for and those against the windmills off Cape Cod is an excellent example of a mammoth propaganda match between two different wealthy interests —just like the Democrats v. the Republicans, and other huge, expensive and utterly undemocratic struggles for the hearts and minds of the majority.
This film is a must-see, as trenchant as it is hilarious, which is really saying something.
