Watch Sadisflix. An Blascaod Mór, Great Blasket Island, is an islet off the southwest coast of the Irish mainland. For years, a declining population and treacherous waters had made life there risky. In 1953, the Irish government evacuated the 22 remaining residents of An Blascaod Mór to the nearby village of Dún Chaoin. This documentary examines aspects of the island's history and literary legacy, and features interviews with former islanders.
