Dark Waters is a morbid version of a much more absorbing tale of fighting big corporations, who knowingly pollute water, causing illnesses, deformities and finally death. That movie is Erin Brockovich made in 2000.

Dark Waters is actually boring to watch, especially the first hour, but livens up a bit in the last hour. Having seen it all before, the best rating I can give Dark Waters is only a 4.
