I just saw this movie in a nearly full capacity packed 300 seat theater. Very rarely I rate 10 out of 10, but this piece of film art blew me away from beginning to end, so what more can a viewer expect out of cinema.
Five teenagers grow up in a very conservative Turkish village. From early age it is expected that they will marry with a boy the elders prefer, rather than loose themselves in foolish romance. What makes the movie so appealing is the outstanding acting performances of the five teenagers and the realistic way the plot develops. Mustang at the same time offers a laugh and a tear; the viewer is offered the perspective of young ladies growing up, discovering their sexuality and being told that this is a bad thing.
Of course some critics will argue that this movie might give viewers a wrong impression about Turkey. This kind of criticism would be the same as stating when a director portrays a story about any kind of bad situation in a certain country, a viewer might get a wrong impression about the country as a whole. This way not one movie should be set in any country in the world because some viewers will always generalize a specific situation.
This movie is clearly set in a small rather isolated agricultural village in Turkey; it clearly isn't set in Istanbul (the more modern capital of Turkey). The director also does a very good job of not pointing the finger towards Islam (the main religion in Turkey).
What is questioned in this movie is not so much about religion, it is conservatism as a concept which is questioned.
A must see movie, one of the best if not the best I've seen in 2015 and the only one I saw in 2015 I rate 10/10.
