look few people really thought that Fk will have no role and it will be all Sonam show all the way. It will be her game changer moment. fawad will be just dissed like any other unknown actor being expressionless, stiff and no future at all comments by all and even critics would not bother to even mention him. But it happened exactly opposite. Fawad may not have the longest screen time , but quantity cannot take over quality. whatever he was given, he performed to the T and got all the accolades. even critics did not ignore the fact that what wonderful expressions this man have. So when their all expectations were not met , they are feeling and, its human nature to feel bad for people we like.
moreover from the starting they were all ranting Fawad is overrated, even seeing his work, questioning why people gush so much. they thought their opinions will be validated by audience and CRITICS which never happened. so this deliberate attempt of writing as much as possible for their fav.
I guess we all do that primarily. when Fawad was getting mocked, we wrote the same thing to let people know that he also matters.
