A Most Depressing Movie

Recently went to see the film Osama. I won't bother to give an outline of the story here as it can be found on the site, Im just going to put down my impressions/interpretations of the film.
It turned out to be the most depressing movie i have seen - at least to my recollection. Though im saying its a good movie in terms of art/cinematography etc, the story and potrayal of events left a very saddening impression. The movie's potrayal of despair and helplessness was very overwhelming. It was like nothing could be done, whatever path the main character took she would end up with some horrible fate.
One particular point where she is discovered to be a girl and all the other children (boys) turn on her to help arrest her showed that the innocence of the childhood in these boys had been replaced by so much hatred - its like the hatred for her as a girl overcame their thoughts of her as a child and one of them in that sense. If these children could be so cruel then one can imagine the extent of thegrown men. Through-out the movie where the girl is in desparation she imagines/or is seen skipping rope something I guess she longed to do had all the cares had been removed from her. Another point that struck me was there didn't seem to be much options available to the women - though at some points in the movie I was longing for her to kill the man and run away, it just wasn't practical for her to do that because all the other wives would come into the situation that forced her to diguise herself in the first place. Another part which disgusted me were the potrayal of atrocious acts commited in the name of God. It seemed like a justification.
Though I know of events potrayed in the film being based on past/present reality it was still very disturbing. Those who are ignorant of these realities would probably be extreamly shocked. I have read critics who say that maybe it is propagandaish or using the film to twist the minds of people towards something, that is one opinion but mine is that it will serve as a good eye opener to some people.
