"The Way We Get By" is a deeply moving film about life and how to live it. Beginning as a seemingly idiosyncratic story about troop greeters — a group of senior citizens who gather daily at a small airport to thank American soldiers departing and returning from Iraq, the film quickly turns into a moving, unsettling and compassionate story about aging, loneliness, war and mortality. Seeking out the telling detail rather than offering sweeping generalizations, the film carefully builds stories of heartbreak and redemption, reminding us how our culture casts our elders, and too often our soldiers, aside. More important, regardless of your politics, "The Way We Get By" celebrates three unsung heroes who share their love with strangers who need and deserve it.
