Black Fish

MUST SEE: Gabriela Cowperthwaite's Blackfish (US, 2013) - A mesmerizing psychological thriller with a bruised and battered killer whale at its center, "Blackfish" goes even further than 2008's Oscar-winning "The Cove" to launch a direct attack on Sea World and the practice of keeping marine mammals in captivity. Righteous, captivating and entirely successful as single-issue-focused documentaries go, Gabriela Cowperthwaite's film draws on startling video footage and testimonies from former orca trainers, building an authoritative argument on behalf of this majestic species. Magnolia and CNN Films have a powerful educational tool on their hands, and would do well to push it into appropriate science-friendly venues beyond theatrical and cable play. 2013SUN. RATING: 8
