Look at it this way. Would you believe a documentary about North Korea as true and honest if it was filmed by the ruling party and featured a child of one of the officials as the narrator?
They could have picked any kid from the street, an ordinary child, to tell the story. But perhaps that would have portrayed Hamas in the bad light? Instead, they lied and picked a boy who most likely is already brainwashed by his family to accept Hamas ideology and their version of events.
Complete wasted opportunity from the film makers to get a true picture of the suffering and disaster brought on Palestinians not only by Israel but also by their own despicable government.
