of the highest order and it shocks to the core." David Parkinson in Radio Times sounds a note of caution: "The methodology employed by Thet and co-director Rob Lemkin is occasionally manipulative and the truth often remains elusive. But this is absolutely compelling, nonetheless." David Edwards in The Daily Mirror is moved by the film's denouement: "The moment when Sambath reveals the price his own family paid is stirring stuff." Ron Wilkinson in Monsters and Critics pays tribute to the journalism, writing, "One of the most amazing investigative documentary films of all time. The interviews are few but of the highest quality." Jared Ferrie focuses on the probative and forensic value of the journalism in The Christian Science Monitor: "In the film, Nuon admits publicly, for the first time, that he ordered the killing of thousands of political opponents, which is probably evidence enough to convict him for war crimes – if he ever makes it to trial." Patrick Barta in The Wall Street Journal found it to be "not only … a historical document, but also … a work of art in its own right."
