A constant state of anxiety makes this a difficult film to watch; it communicates the anxieties of a parent for the well-being of their children very powerfully. Will they get lost? Will they get run over? Will they drown? Achingly terrible fears arise out of the most mundane circumstances. The acting is fabulous and the city, itself, is beautifully filmed, so that it becomes integral to the feelings that are created. The family relationships are truthfully portrayed and the effects of grief, expereinced in different ways by each of them, is beautifully explored without a hint of sentimentality. This is a true gem of a movie.
