“Of Fathers and Sons” follows the daily lives of an extremist family.  Filmmaker  Talal Derki posed  as a sympathetic  photojournalist  to  enter a village controlled by the al-Nusra Front in the Syrian Civil War and stayed with the Osama family for two years. The father  works as a sniper and as a mine remover.  He removes his children from school due to coeducation and latter sends them to a terrorist training camp.  The older son embraces the cause; the younger wishes to return to school.  Derki’s “admirably audacious feat” took home an  Oscar and the Sundance prize for best documentary.
