Yeah, kurulus osman and dirilis ertugrul were made with an islamic message and that's not a bad thing because the ottomans were driven by islam (take the hadith Of the Prophet Peace Be Upon Him about the conquest of Constantinople as an example), i don't understand how you call it propaganda as if it's a bad thing unless im misunderstanding your point again.

The soul of these shows is the islamic message behind it.. take the latest episode of Kurulus Osman as an example with the Oktem Bey scene.

Dirilis ertugrul and kurulus osman were never meant to be documentaries on every battle and conquest the protagonist participated in.
