All of Salina's interviews and data tell a graphic story about corporate water piracy, the complicity of governments, the burden put on the poor and the scam of bottled water. But she can't quite jam it all in and still have a film that, well, flows.
The inconvenient truth at the center of Flow: For Love of Water is that while the oil crisis is intensely debated and documented, disasters involving an even more essential fluid go perilously unnoticed.
You'll never want to buy a bottle of water again after seeing this essential documentary about the blatant theft being committed by companies like Nestle that have helped make water the third biggest global industry behind electricity and oil.
Although meandering at times, Flow is still a serviceable documentary spouting daunting informational facts and figures about the freshwater supply threats and the perilous consequences that inevitably follow.
Along with this sobering information, filmmaker Irena Salina's docu includes a distinct note of optimism that should help the film flow smoothly through the festival pipeline before eventually settling on DVD.
Flow is the kind of terrifying, impending-apocalypse documentary none of us wants to watch but all of us probably should; it isn't the most enjoyable experience you'll have at the movies this year, but I wouldn't doubt if it's one of the most eye-opening.
