This protracted documentary has theatrical standard filming and a significant subject going for it, battling a reluctance to trim it's material to a length any but the most determined film festival subscriber will support.In three Third World locations, too much or too little water creates misery. Bangladeshishis move their corrugated iron homes out of the path of land-eroding floods. Kazahks live on a dried up sea bed and, in Nairobi,getting drums of water from unreliable tap proprietors bears down on the slum people.Good colour and a nice score. Captions in place of commentary.
