This film follows other films like "Lord of War" and "The Constant Gardener", highlighting the problems faced in africa by setting a fictional story against the backdrop of the continent's problems.
And it does it well. The cinetography is great. The plot holds together. But best of all - the characters are relativly three dimensional.
Everybody in the film doesn't suffer the fate of being "bad" or "good" or even "wonderfully callous." They're all self motivated with their own goals and desires which are mostly self-serving even if we would normally consider some of them "good" and some of them "bad".
As such, rather than being a simple morality tale there is at least merit in watching the transformation in the characters during the ensuing maddness brought about by the state of afairs in the film.
Not bad. Worth a watch.
