Is the film one-sided? I'd say it is. But were the CNN, CBS etc. reports less one sided during the war? Unfortunately - absolutely not.
So, the film is not repeating the stuff everybody in the West already heard about? Is it really that strange? It tries to use the time it has to show the side of the truth that was not presented before, not to repeat what's already known. I am not trying to defend it, because I don't like one-sided movies myself... but I do understand the intentions. This was not made by a neutral observer - this was made by a man who couldn't stand the selectiveness of the "truth" presented. That's why this is not a great documentary - but it definitely should be seen.
The real question should not be was it one sided, but was any of this true? Because if it was, you should ask yourself - how much the "truth" you hear every day is filtered, so that you can hear only what you as a viewer and a voter are wanted to know, and no more than that. Especially about foreign affairs. Because reporters are much more ready to turn the blind eye on sufferings of people of some foreign nation when asked to, not so much when it happens at home.
I cannot say for sure if everything in this movie was true. But I can say that some things definitely were, and that those things were never presented in US media. I have heard about some of those events earlier, from my friends or relatives witnessing them. I even witnessed some of that myself when I visited Bosnia and Serbia.
So, just watch it, don't believe it. Then watch the reports from the other side about the same events, and compare them. The truth is often somewhere in between. It is sometimes amazing how some things start to get much more sense when you get a chance to hear another side, too.
Normally I would give no more than 6 to this documentary... but since some commentators gave it one star simply because they don't believe the stuff presented there, I gave it 8. Because it really should be seen.
