The majority of critics have no clue about the significance of the events carefully crafted in this truly Italian opereta. I was 18 when this happened and it looked absolutely insane looking at this from America. Fortunately I speak Italian and actors are just fantastic. I will give special credits to Francois Cluzet, one of my favorite French actors. The events are those that happened that year of revolts in France and elsewhere, while this engineer Rosa makes the impossible to pass the same message with technology.
