  1. This documentary makes a terrible kind of sense. It reminds us that something we take for granted, like air, can be sold to us – if we can afford it. And if we can't, what happens then?

    According to Irene Salina's eye-opening documentary Flow, 500,000 to 7 million US residents are sickened by tap water each year.

    A very effective primer of an underreported problem.
  4. 75
    Skips right past depressing on its way to apocalyptic.
  5. Reviewed by: Vadim Rizov
    One of those charming little documentaries that make you question whether the human race is really worth preserving.
  6. A smartly done, involving look at a number of interrelated water issues.
  7. Irena Salina's astonishingly wide-ranging film is less depressing than galvanizing, an informed and heartfelt examination of the tug of war between public health and private interests.

    It's strange thinking of water as a market commodity, and it's hard to comprehend the kind of greed that must go into keeping it from needy mouths, but, fact is, the water business is now the world's third-largest industry, meaning there are a lot of sinister souls out there fiddling with their bank statements while Rome dries up.

    Flow preaches to the choir with a starry-eyed NPR eco-humanism that can set the wrong kind of person's teeth on edge.
  10. Reviewed by: Justin Lowe
    Insistent, sometimes conspicuously one-sided, the film's concerns are difficult to dismiss, considering that a water-starved planet isn't ultimately viable.
  11. Flow makes you thirsty for more information.

    Builds a strong case for the conservation and preservation of water as a free resource for the world. Its warning against corporate ownership of water as a saleable commodity is stark. Overstuffed with information as it is, it fails to mention at all the disappearing Great Aquifer of the midwestern U.S., a strange ommission for a film of this scope. Full Review »

    Fair documentary, it's interesting but it does get repetitive and it isn't out of the ordinary. Well filmed, good interviews. It doesn't always convince however. Full Review »
