The film focuses on humorous (and often surreal-grotesque) manner very serious social phenomena such as loyalty, opportunism, patriotism, brotherly love, etc. - and all this against the backdrop of the political developments in Yugoslavia since the end of WW2.
The film lives especially of the immense energy and enthusiasm of the leading actor Miki Manojlovic. Manojlovic embodies the arms merchant and war Marko, the multiple political and military fronts changed in the time between WK2 and the Yugoslav civil war of the 1990s and thus added continuously gaining power and wealth. "Underground" is - despite its considerable length of 194 (shortened: 165 min) min - never boring. For this does not contribute insignificantly the phenomenal music of Goran Bregovic at: it is throughout the film latently present and will take place during a wedding scene a furious climax. Who has not made any acquaintance with the (Blechblas-) music of the Balkans, which is experiencing its true musical prodigy here ...
Conclusion: Before an extraordinarily serious historical background the director Emir Kusturica succeed a bitter satire on political opportunism in the times of war and the (socialist) dictatorship. Here Kusturica Weisz constantly full of surprises but grotesque symbol-laden scenes. Some of these scenes from the "Underground" are so concise that it is the audience probably never forget.
