The Anglo-American West was supporting Miloshevich and his Serbian hordes (parading as "JNA") during the first year of the War of the Fall of Yugoslav Federation of the 1990s. They expected Croatia to fall, but the commitment of the Croatian defenders was too much for the rotten, poorly organized, corrupt and viciously criminal Serbian side in the War in which Yugoslavia exposed itself to the world for what a fake nation it was.
This movie is attempting to authentically bring to the screen the reality of the vindictive Evil that Serbia unleashed on Croatia in 1991 thanks to the deeply criminal and psychopathic Serbo-Montenegrin Communist Regime of Terror & Lies based in Belgrade, and led by the fat-cheeked President Miloshevich.
The acting in the movie is decent, the scenes are authentic, the psychology of the warring parties is fairly accurate. The Croats defended their nation that they loved, while the Serbian invaders were primitive losers and wannabe Chetnik rapists on a mission to ravage Croatia and satisfy their sadistic lust for rapes and abuse of the hated Croatian civilians.
The movie serves well the purpose of portraying the basics of the 1991 Battle of Vukovar, the last classic full scale battle in Europe in the 20th century.
