Long ago and far away, the fictional Swiss Family Robinson carved out an idyllic life for themselves on a tropical island. As Radu Ciorniciuc’s deeply embedded documentary begins, the Romanian family Enache — father Gică, mother Niculina and their nine children — seem to be doing something similar. In sun-flared shots, giggling, lithe, rough-and-tumble kids pull fish from lake waters with their bare hands and set switches of wood aside to dry, so they’ll be ready for use as fishing rods “by next year.”
