Eventough it is really meaningless on one hand, on the other hand it was quite interesting.
What makes this movie unique is about the Tengri belief. Turks believed in single god even before Islam. God was called the god of the skies and all universe as his creation.
This movie is nothing even close to todays beliefs and can not be categorized as a propaganda because they are not usual muslims. They do magic, they pray as shamans, they combine Islam with Tengri which may be categorized as being close to Alevi belief in Turkey which todays ruling party hates.
So, I think this is a fantasy movie which has no meaning other than showing some blood and some Tengri.
And probably if the guys were named as Vikings, the movie may have been more meaningful :).
