First-time documentary maker Rebecca Richman Cohen looks at the civil war in Sierra Leone, a conflict in which countless civilians have been raped, mutilated, and murdered. Making a film about atrocity that’s both responsible and artful is a tough challenge, and Cohen reacts to it with a lot of empty style. The movie jumps from explanatory interviews to impressionistic montage to purposely distressed news footage that evokes avant-garde video art, but there’s no apparent rationale behind her grab-bag aesthetic. This is certainly informative, and as filmmaking it’s never boring, but Cohen’s desire to keep the viewer entertained seems distasteful in hindsight.
