Characters = cliche idols, sometimes a bit boring as an reanactment and dull, as it is state cinema of the Breshnev aera. BUT:
So spectacular that even big cat Hollywood executives get pale watching this. It is unique in the moments when the choreographies become breathtaking, taking you back in time. Fine Ending, of course.
Why is it listed as polish film? It was done by the Soviet Union, Poland and East Germany.
