I have read your complete post and have already watched complete Ertugal series, all 74 Episodes. In my opinion, this series helps to build a strong character, helps to boost a Muslim's moral. It may help the Muslim Nations to come out of inferiority complex. It may enhances one's trust in Allah.
It gives an opportunity to know about Muslim's History, their achievements and opportunity to learn from their mistake.
Having all that said, every thing has its Pros and Cons, its our leaders responsibility to utilize youth energies toward positive causes. I guess, this is what Imran Khan is trying to do and the corrupt mafia is trying to create hurdle in whatever steps he is trying to take.
