While “Super Big” details Leondro’s difficulty growing up without a father, its main focus is on his good fortune in having a mother who shouldered the burden. As a single parent, Leondro’s mother fought to keep her children out of trouble while still providing food to eat and a roof over their head. “Super Big” is from the perspective of a man who is only now able to fully understand and appreciate the full scope of his mother’s sacrifices.
