Ever since the premier at the Toronto Film festival critics and viewers have been raving about this low-budget gem. A lot of people go as far as calling it a life-changing film, and rightfully so.  It tells the story of three people from different parts of the world who face new ethical problems caused by a change in their body: a blind photographer who finally gains sight; an animal rights activist whose newly diagnosed liver condition requires treatment that involves animal testing; and a man who, after having a kidney transplant, learns about the black market for organ trade. The title refers to the paradox that asks if all parts of a ship are replaced, does it stay the same ship? A beautiful intellectual exercise.
