this be a great movie about the cambodian genocide . refuse any sensational or sentimental approach and it be just make out of testimony and and patiently and slowly try to understand how such a thing could happen . the mechanic of the khmer rouge crime and the paranoiac will to obtain ( by torture ) a reason ( completely absurd ) to kill their victim be terrify . and testimony of the torturer be strike of refusal . patience and the intelligence and the firmness of one of the rare survive victim give again fortunately confidence in humanity . this movie be make on a similar approach to claude lanzmann shoah . which mean to place the testimony in the center and and refuse any reconstitution or archive image . maybe the only way to speak about such an event .
