Post 9/11 Americans were told that the jihadists were monsters and inhuman - Abu Ghraib and Gitmo ensued. The movie tests our assumptions about how and why people do monstrous things.
The movie was made with remarkable access to a rehabilitation program in Saudi Arabia about four former jihadists. Audiences probably remember when Gitmo detainees were released to Saudi Arabia that the press cast doubt that jihadists could be rehabilitated. The movie asks a similar question but through the lives of the four jihadists.
The movie humanizes the men by showing how young they were when they were radicalized and headed to Afghanistan and other locations to wage the perverted jihad preached by mullahs.(America had a few who answered a similar call - see information about frank lindh's son ). But, through interviews and other engagement we learn how persons who have done monstrous things need not be monsters.
The movie dispels the slander that the movie is Saudi Arabian propaganda or that a white female filmmaker could not make a movie about Arab men. The movie is ultimately about truth - which any documentary should be.
I think that there is another documentary here - how the documentary field has been hijacked at times by activists who suppress expression rather than engage with it.
