Gees U have hit the nail on the head...I too was thinking on similar lines...MB as the Ashu of old was suave, sophisticated, and a master of emotions when he was in the initial stages of the falling-in-love process...But the way Ashu's character has shaped up since the V-Day, Delhi and accident track I feel SK is doing a splendid job of it...I have my doubts if MB would have been suited to play this new Ashu as he was to the old shy and reserved one...
As for Nidhi the least spoken the better...She has literally paled into insignificance over the last few episodes...her dead-pan face, devoid of any emotions does not depict a girl going thru such a terrible trauma in her life...The least the CVs could have done was to show her breaking down at least in front of Ashu...That would have been more convincing and the viewers would relate to her trials and tribulations and cry with her...Here we cry for Ashu and am sure most of us are saying Ashu is well rid of her...CVs pls take a hint and make Nidhi's character more realistic and one we can all relate to...
