Directors Kristi Jacobson and Lori Silverbush cover a lot of ground in their heartbreaking documentary examining the hunger experienced by nearly 50 million Americans, but at less than 90 minutes, it feels a bit overstuffed. Even though they focus on three separate individuals — Rosie, a second-grader from Colorado who can't concentrate in school due to stomach cramps; Tremonica, an overweight second-grader from Mississippi who's on a diet of empty calories stemming from the cheap, processed foods that her single mom barely affords; and Barbie, another single mother who dreams of providing a life away from the poverty she grew up with in Philadelphia — they hit their bullet points over and over. "Food insecurity" is how this film from social-issue producers Participant Media refers to the growing epidemic of malnourishment. Well-nourished Tom Colicchio of Top Chef and actor Jeff Bridges lend their testimonies to the human stories of hunger.
