Everything was fine till 200th episode but after that it seems that the story writters ran out of new ideas. Old episodes are really funny and it relate to problems faced by common people everyday. With rivalry between two people in society, quarall among them and then resolution of tension to a friendly relation between the society members. Eventually characters persisted an ever happy attitude which ultimately made show boring. It lost its originality.
It seems like their aim is shifted to extend the story as much as possible. It is becoming more like "sas bahu serial".
