As much a horror film as a politically-minded documentary, this amateur outing follows the journey of Josh Fox to investigate the effects of natural gas drilling when he is offered a sizeable sum to make his land available for the process. Uncovering in his travels across America water so contaminated it goes up in flames, animals so unhealthy their hair has begun to fall out, and people suddenly subject to frequent headaches, Fox quickly turns from casual storyteller to activist when confronted with the staggering injustice of these unaddressed outcomes. With the same sort of intimately personal narration that made Dear Zachary so compelling, Fox presents educational information with an emotional edge, weaving humanity into the abstract facts in such a way as to make them fascinating to study. A skilled visual artist additionally, his use of a variety of landscapes adds a scenic beauty to the film that transcends the technical limitations of its impromptu film crew’s equipment.
