well keep in mind that Umera wrote the script for this as well. And I believe this one is fairly close to her heart.
But I do agree with you that it was a little over the top as far as emotions. On the other hand, the novel is quite emotional. I don’t think there were any light moments in the drama except for the Haider+Saba’s daughter interactions 
I do remember crying my eyes out when reading it (dang those emotions! ;))
Now I just hope they don’t turn it into a 15 epi serial - yuck!
