This is exactly what I was concluding during these last days : if it's turkish propaganda, they shoot themselves in the foot .Yep. And that's why I think it ultimately fails as propaganda. Critics of the Ottoman Empire, or Erdogan, can simply use it to say: "Look how far the mighty have fallen; they're obviously not living up to Etugrul's ideals." I saw a YouTube comment recently to this effect. The guy said something like, "Turkish leaders like Ertugrul don't exist anymore."
Now people can compare with their original values and what they have, what they can see.
This series does a good job, sends a beautiful message to Turkish people, to muslims, and finally to all : it demonstrates throught long, detailed and lenghty examples the eternal fight between good and evil. Maybe I'm stepping too far but i see this a strong STO move in these times of major disclosure. Here, the message sent is not done the usual way which can be seen as having an active reaction/response to what is happening nowodays (denounce the lies, exposing the guilties, arguing on 1001 facts), no, here it's a passive but incredibly strong message based in one hand on exposing how "bad people" act, and on the other hand on inspiring by the example, by giving food for the original human's values which are present in any (normal) human being. (I see this like watering the seeds present in many people)
When you think twice about Lizzie's spirit, this series goes on the total opposite, it exposes the psychopaths at length and in depth, but also shows how to counter them mainly by showing, by the example, how to improve one's good qualities (honesty, patiente, tolerance, discernment, trust, faith, ... and many other... even the benefits of "networking between good guys'" is well demonstrated) ... it's indeed brillant.
C's said a lot of time that help is on the way, may this series be part of this help ? This "way of doing" nicely fits with the way STOs act.
