A consistently tight legal drama which brings to mind the very best of its kind (…), from a layered screenplay which delivers a story to believe in and people to care – and fear – for (…). With very few bells and whistles – even significant plot breakthroughs are dealt with a breath-holding restraint – Dark Waters is a palpably well-made feature (…). This quietly galvanising film – in subject, tone, and treatment – harks back to the powerful social issue dramas of the 1970s, another time when the world felt besieged by corruption and abuse of power.
