Don't expect much psychological depth, over analyzing about the war, certainly none of the liberal aspect that filmmakers tend to take when they want to question the reasons behind the war, or at least show the "bad guys" state of mind justifying in some way their actions, if you want that, there is a great movie about war in Bosnia: Ničija zemlja. This is something different, one heroic battle.
It is based on actual heroic battle in small village in Croatia, crew did an excellent job of bringing that event to life, rifles, uniforms, acting, village... all is of unquestionable quality. There are as well few nice details, that add to authenticity, like rosemary around the soldiers neck etc. Unfortunately some of it will just Croatians appreciate to full extent. Director is keeping it simple while still in few lines explaining everything you need to know about this war. Most of the attention is on the battle, anxiety, comradery and war tactics (or the lack of it, most of those Croatians were rookies, as were Četniks, who were on top of that mostly drunks), there is just a little interaction between characters before the battle, it is simple and just enough, while we learn basic stuff about characters throughout the battle. There is a lot of slow motion explosions and gunshot wounds that look amazing, there is even first person perspective in some scenes, it all adds to very high paced and dramatic atmosphere, while remaining amazingly realistic. There is no dumb action movie scenes where the guy is shooting, and then we see thousands of bad guys running around like idiots and dying. Most of the rounds are shot completely blind, some even without aiming, nevertheless in real war there is much more suppressing fire that doesn't hit anything, even in close range. Dialogue is fantastic, minimalistic but still enough realistic that you actually believe that they are real people in real war.
It is a real hard core war movie, with all the drama that follows, that we Croatians have been longing for. Not to say that previous have failed, but none has shown the fierce action and/or have failed short dragging you into the hell of firefight in the Croatian War of Independence. At times it will make you laugh, at times it is grim and ruthless as it comes (followed by excellent gloomy music), and I don't want to sound overly pathetic, but it will make you feel proud.
Overall great action, great drama, authentic... Stop reading this and go watch it!
