In the artificial landscape that is Los Angeles, where even palm trees are imported, nothing epitomizes man's short-sighted efforts to reshape the face of the earth more than the LA River: modified beyond recognition, its flow tapped before it even reached the surface, the river was used, abused and essentially forgotten. But when an unassuming boater insists on seeing it as a river again, a local controversy takes on national dimensions, and the once-derided eyesore turns into a source of hope for the City of Dreams. 'Rock the Boat' is a fun, high-energy and, ultimately, moving film that tells this every-man's adventure and looks at the price nature has to pay for our urban lifestyle.
