This is a great film about integrity, personal ethics, persistence, passion and courage. It's beautifully rendered in all aspects. And it is sombre. It has to be, because ***Spoiler alert*** good does not triumph over evil. What makes this film so important is that it deals with reality that ordinary people are for the most part powerless against the interests of powerful, profit-driven companies. Teflon, and all the horrific by products of its production, continues to poison our homes, our communities and our planet and there's nothing we can do about it. It's a tough message for a film to bear, but Dark Waters does it beautifully, elegiacally and most nobly.
