Writing about the film in Harpers Magazine in 1969, the critic Pauline Kael declared it, "hell to watch for the first hour...exciting to think about after because its one good sequence, the long picture-postcard sequence near the end, is so incredible and so brilliantly prolonged. The picture has been crawling and stumbling along and then it climbs a high wire and walks it and keeps walking it until we're almost dizzy from admiration.The tight rope is rarely stretched so high in movies..."

The renowned author and critic Susan Sontag referenced the film in her 1977 collection of essays On Photography. With respect to the "two sluggish lumpen-peasants" returning home bearing postcards of the treasures of the world instead of tangible treasure, Sontag noted that "Godard's gag vividly parodies the equivocal magic of the photographic image."
