"There are many documentaries angry about the human destruction of the planetary peace. This is one of the very best — a certain Oscar nominee. It includes a great many facts about the craven International Whaling Commission and many insights into the mistreatment of dolphins; Simon Hutchins, who has specialized in the subject for the London Telegraph, is especially helpful.
But when all of the facts have been marshaled and the cases made, one element of the film stands out above all, and that is the remorse of Richard O'Barry. He became rich and famous because of the TV series, which popularized and sanitized the image of captive dolphins. He has been trying for 25 years to make amends."
