'Crude'

"Crude" sounds like the standard "this is an outrage" environmental degradation documentary, the latest in a line that includes "An Inconvenient Truth" and films about the death of the ocean, the evaporation of water, the murder of dolphins, even the disintegration of dirt. "Crude" fits that bill, but it is something considerably more interesting as well.
