As said in the other comment, it is rather difficult to rate a movie like this as a piece of art, but it has nevertheless a role as a witness of the crimes described.
As such it is extremely important, especially in a case like this, when it is about a civil war most of us don't know about and which is probably one of the most horrifying. (By a group of experts it has been named the second worst "forgotten humanitarian emergency" in the world, right after the conflict in Congo) The war between government troops and the "Lord Resistance Army" is now ongoing for more then 19 years. While the "Lord Resistance Army" has never stated any clear political aims, they are terrorizing the population mainly (but by far not only) of the so called "Acholiland" (named by the Acholi people) for two decades now. Their methods include the mutilation and slaughtering of the people but also the kidnapping of children who are then forced to kill as soldiers for them. Since the outbreak of the conflict in 1987 there have been killed more then 12,000 people directly by troops of the "Lord Resistance Army", not to forget about the thousands of people mutilated, raped or just made homeless refuges. Nearly two million civilians have been forced to leave their homes.
The movie mainly concentrates on the role of children in this conflict, who get kidnapped by the "Lord Resistance Army". They are made "child soldiers" and are forced to kill and mutilate other civilians, often children or even family members. Some of them can finally flee from the conflict and are in a lucky case then taken up in a Caritas lead home for kidnapped children. The movie follows mainly 3 of these child's, showing how they try to reintegrate in their society and forget about the war. Most of them will probably never succeed in both, not at least because the country is still dominated by the conflict. Their families are often afraid of them, telling stories about child soldiers having returned and then killed family members. They are either accepted at home, nor in the public, where they are equally feared and afraid themselves, since there is always the threat that the "Lord Resistance Army" could come back and kidnap them again or just kill them and their families.
Since there are no interests or causalities of western countries involved in this conflict, there is little or no media coverage. If you want to get an impression about the things happening in Uganda since the outbreak of the war two decades ago, you should watch this movie.
