I just think this show is losing its charm. Some of your comments are correct about braces being worn for a short period of time. Truly any intelligent person who works in a fashion house would become conscious of his/her looks and would improve on the looks.
In a country where fashion symbolises culture and fusion of the East and the West it is simply difficult to believe that a nerd such as Jassi would not change.
This series is childish in a lot of respects. It continues to emphasize very childish relationship(s).
Viewers felt that Jassi and Nandu epitomised Indian middle-class and seemed to portray the challenges faced by this particular class. However, the Indian middle-class is probably the most forward looking and hence really what Jassi and Nandu epitomise is a very small percentage of the Indian society.
The producers have failed to understand a very basic fact about Indian viewers. You need to change the plot to keep viewers interested. There was a moment when viewers waited intently for a good looking Jassi to come on the show. At present, I couldnt really be bothered if a good looking Jassi came or not because the show is just boring.
I havent watched this show for over three weeks and it makes no difference now whether I see it or not. The reviews are interesting however.
Pity, the producers have not managed to keep the interest.
