A carpenter alarmed by the rise of McMansions, adding to habitat density and waste of resources and energy, on his privileged island enclave of Martha's Vineyard, took up a video camera and documented his story over a dozen years.It is on its own terms a commendable piece of journalism, and reaches out to potential viewers who are not part of the filmmaker's well off white community, when it touches on interesting history.Such as a groovy time when the island was a hangout for naked hippies.Or the background of the indigenous Wampanoag tribe who were forced to give up their communal land holdings (another meaning of the title One Big Home) when the state made them citizens around 1870,,but made them also divvy up the Commons into individual plots, leading eventually to the natives being supplanted by whites.and something is said about the laborers on these monstrous new buildings who benefit by making more money so they can still afford to live there.But for most of the running time, the viewer is challenged to feel much sympathy for the elite such as newsman Mike Wallace and director Doug Liman who spend time there.And when the carpenter himself builds a bigger home we are disappointed that he has caved in.one reason the film has not seen that much of a release is that it speaks to a rather narrow clientele.
