Last month, “The White Helmets” took home a much-deserved Oscar for Best Documentary Short. It’s not the sort of film that reinvents the wheel, nor is it a particularly grand feat of filmmaking. What it is is an extraordinary glimpse at an urgent and overlooked crisis, a film that manages to find the human capacity for love amid the horrendous onslaught of war. Without a doubt, it was the most important film in its category. “Cries From Syria,” is, in many ways, an expansion on “The White Helmets,” a feature-length look at the war — a film that, while not especially pronounced in its structure or technical achievements, is nonetheless timely and devastating.
