My brilliant friend displays complexity of human feelings, it indicates what women go through in marriage with some one who they don't truly love as a partner, there is a boarder between men and women in this series which I don't know if it actually exists or not, but the show claims male and female's nature and their entity are deeply different. it's not a fancy world, the characters are real humans, as complex as humans, every character is doing what it comes from deep inside of them, there are parts u witness true self of them and mostly they are heart breaking, u witness thoughts that there are in their mind while they don't want them and still they can't push them away, those thoughts exist in their minds whether they're not nice or right or wanted thoughts , the show does express how humans are indeed, it's spectacular. A true masterpiece.
