Sean Baker’s The Florida Project (2017) presents a blended family dynamic born of poverty. The protagonist, six-year-old Moonee, lives with her young, volatile mother, Halley, in a budget motel outside Disney World. Their chosen family is the motel’s manager, Bobby (Willem Dafoe), and the other transient children. Bobby functions as a surrogate stepfather—disciplining with weary kindness, covering for Halley’s mistakes, and ultimately failing to save the child. It is a devastating portrait of how blended dynamics can emerge in the cracks of the system. natasha nice missax stepmom
