A grerat and scary movie about radical Islam in Central Africa: Timbuktu

Abderrahman Sissaako's (yes, I had to look it up) 2014 film, Timbuktu, is scary in all sorts of ways - not like a horror film and not because of excessive violence but because it shows, as clearly as any film I'm aware of, how a radical Islamist force can sweep into a small city, seize control, and impose its autocratic rule on the terrified, cowered residents. A bunch of thugs with guns will rule - there seems to be no way around this - unless they're met with equal counterforce by a central government, and none seems to be present or even rumored, in this film and on the ground today. There are a lot of dimensions to this movie, some a little hard for Western viewers, or to me at least, to unravel - there seems to be an opposition, even before the arrival of the militants, between a native black culture and a Bedouin culture (the movie is set in Mali, where from what I've read there are African-Bedouin struggles, essentially a war between South and North); not quite clear if everyone in the small, invaded city is Muslim, but that appears to be the case - but the invading thugs impose a strict regime (women covered, even to the point of wearing gloves at all times), on all but themselves (smoking is banned, but the leader of the invaders finds a place to indulge). Some of the villagers resist, and some are punished, lashed, even killed for their upstart behavior. Film centers on a Bedouin man who kills an African in a dispute about stray cattle v fishing nets - and on his so-called trial and execution; odd that this infringement is peripheral to the radical invasion of the city, but it shows how the invading army perverts the entire justice system in the name of jihad or shariah. The radical Islamists are not driven, it seems, by faith or by any desire to make lives better for anyone but themselves - in fact, the driving force seems to be about oppression of and possession of women (my belief is that the whole extremist culture in Islam is driven by the harem system, which ensures that there are not enough women in any one village for all of the men - creating militant bands to protect the harem and that go off in search of women in other villages whom they can capture and control). Can anyone explain who the man is whom we see in the opening sequence being led blindfolded to an exchange place in the desert? One incidental pleasure of this film is the great score, with original music by Amine Bouhafa (yes, I looked that up, too), much in the tradition of the great Ali Farka Toure. If there's a soundtrack CD I will buy it.
