A slick piece of work, Guerreros follows a few tense hours in the lives of a group of Spanish army engineers stationed in war-torn Kosovo. Sent on a mission to restore an Albanian village's power supply, the idealistic peacekeepers soon get sucked into guerrilla fighting between the Serbs and Albanians. Directed with shallow flair by Daniel Calparsoro, the movie boasts the bells and whistles of a state-of-the-art Hollywood production. The grandstanding direction may strive for maximum gloss and gore, but Guerreros can't help but be compelling anyway for the relevance of its subject. Opening with the cold-blooded murder of Albanian civilians by a squad of Serb paramilitaries, the movie initially seems poised to be a screed in favor of humanitarian intervention. As the body count piles up, however, the movie's ambivalence about military peacekeeping becomes more pronounced. The slide down the slippery slope of good intentions seems to suggest that interventionism can only lead to disaster. But given the harrowing massacre with which it opens, it's a conclusion that seems confused at best. Perhaps too concerned with the logistics of battle to think the issue through, Guerreros is afflicted with the very qualities it criticizes: an earnest heart, but a muddled head.
