In my opinion, the film is flawless! A mixture of black comedy with tragedy, Underground can really touch you deeply. It displays clearly the tragedy of war and the vanity of human nature. Don't get discouraged if you are not familiar with Balkan history. People are all alike; you'll recognise the patterns easily.
Finally, the music is great. Goran Bregović wrote on of his best soundtracks! Some songs, such as "Mesecina" and "Kalasnjikov", are already classic!
A moving requiem for a dying country. A cult film that will probably mark the history of cinema forever…
