No one is born violent or extremist, they are made. The movie focuses on conveying the message that violence and extremism needs to be stopped at the root level. The world seems to be focused more on stopping the terrorists once an incident takes place rather than putting the stop on causes of production of terrorism.
This film highlights one of the root causes of young minds idealizing terrorism which is mainly due to parents not giving proper time to their kids. Kids playing violent games and watching violent films may have higher probability of becoming violent as they grow.
