As an Iranian viewer of the series who is anti-Islamic Regime of Iran, anti-Saudi Regime, and anti-Zionist Regime (not to be mistaken with anti-Israel or antisemitic), but pro-Iran, pro-Israel and pro-Saudi, I found the series quite entertaining and intriguing. There might be some hidden bias or inaccuracies which is normal and acceptable. Kudos to the production team for creating something unprecedented.
I just read that some Iranian commenter has written that the Israeli spy game is in Iran is not as complicated as shown in the movie and I totally disagree with that. It was only 2 days ago that Israel hunted a big-shot Iranian military figure inside Tehran (Mohsen Fakhrizadeh). So as you see, it's much more complicated on both sides.
I hope one day this craziness leaves the Middle East and people can leave peacefully and tolerate each other and learn from each other because any nation has its own beauties no matter what. And after all, we are culturally very close. Viva Iran; viva Israel.
