Christian Frei set out with his camera to explore the current situation in Cuba, the result being a documentary that is sustained by powerful images, that testifies to technical skill, a professional way of dealing with the material and, most importantly, a carefully deduced and clear message: the two protagonists, Ricardo and Miriam, reflect the tension between a revolution that has already turned into history and the present that in fact seems to be taking place elsewhere. The Swiss film critic Norbert Creutz has estimated the objectivity and the formal quality of the film: In keeping _his_ distance and seeking greater objectivity, Frei highlights contradictions and paradoxes while being careful to avoid taking sides. <sep>, Pronoun: his <sep>, A: Norbert Creutz <sep>, B: Frei
