Three years after Josh Fox explained and explored the issue of fracking in his 2010 documentary Gasland, and showed a resident lighting his contaminated tap water on fire, he’s back with a sequel. And this time, he travels across the country – stopping in Texas, Colorado, Arkansas and elsewhere, as well as his native Pennsylvania – to show how natural gas companies are using political influence, public relations, and lots and lots of money to continue and expand their practice of subterranean natural gas extraction. Each new segment of Gasland Part II brings another outrage – and at the end, when the focus becomes global, it also becomes downright scary. An important sequel to a movie about a subject of more interest than ever.
