I only watched season 4, mainly because I wanted to watch Murat Yildirim. He did not dissapoint. He is such an incredible actor and he can truly play any role. His relationship with Zehra was actually really entertaining and honestly what made me want to keep watching. They had great chemistry. However, after a while, the formula of the show was very obvious. Conflict, mission, conflict during mission, tough decision made, mission successful. I dont know if this is true for the other seasons, as I havent watched them, but I will admit it did get kind of boring after a while because I could see how things were going to transpire as it began.
