there are a lot of stuff that i agree with you about , esp about dia being neglected and all that.
maybe in retrospect i do agree but when watching it on a day to day basis the feelings were different - like i didnt like dia too much though she did transform later on- i found too many things started and left in between which used to irritate me but all in all now in retrospect its only the beaytiful relations that is still fresfh in the mind like u pointed out the non romantic relations were very well shown.
the one thing that i find difficult to agree with you is the sam- nup bond. it really wasnt much compared to the other bondings, it was always gun- nup first, mayank- nupur or sam- gunjan next (depending on whose fan you were) and then mayank- samrat. later on it was sam- benji/ sam- nup/ sam- dia and so on. sam -nup was most imp in season 2 only though like u many liked the two together.
keep writing maybe about individual tracks as someone suggested!
