The interactions, particularly in Kabul are outstanding. This is definitely an area that is new to almost everybody because the major media has ignored it. When the more main stream TV correspondents go out and interview, they have a ton of equipment and plenty of armed guards. This had a much more face to face with reality feel to it. Wherever parts of it were filmed and however it was done, it projected a sense of constant danger which I suspect comes far closer to the reality of the situation than many are ready to admit.
People who like to ask the question of "why haven't we caught Bin Laden?" ought to get a sense of what we are up against after seeing this movie. And have a lot more respect for our small unit special forces who have fought and lived in this environment for years now.
Who is friend? Who is foe? Who knows exactly what is going on? The whole point of the movie is that all this is not laid out as simply as most Hollywood productions. And that point ought to be well taken.
None of the characters were particularly likable (although the cameraman comes close). But I think that was part of the point. This was not Rambo, nor was it Mother Theresa goes to save the world. The environment overshadows the individuals. Get it? Finally as far as the rather far fetched plot (certainly the ending is a stretch -- I hope that's vague enough not to be a spoiler), it's almost incidental to what the rest of the film conveys. It would have been a rather short movie if it were realistic and all three protagonists were killed in the first five minutes of the film.
