This is by far on of the best series.
So far I have only watched three Turkish series, and out of all of them this is probably the one I like the most. Kurulus Osman was also a very good series but I would rather watch this due to the storyline.
Some may argue that they like Sanjar for his bravery or Turna for her beauty and etiquettes as their favorite character, but after re-watching all the episodes until now, I've come to the conclusion that every single character is lovable or interesting. Even Hassan Sabbah, the merciless Batini who killed millions of innocents, was brought to life with his fearlessness, his funny expressions, and over all his cool vibes.
And I'm pretty sure anyone who has watched this series would give at least 4 stars. I would recommend this show to many people and would for sure watch it myself another time later on.
