hey...
i agree on some points.. umm I liked Sudha Chandran as Mallika but at the same time felt she is very young to be playing such a stagant role... i mean she really didnt do much that showed her wonderful acting abilities, so in a way Anju Mahendru is a gr8 replacement because, for her, she has done so many roles that playing a mother comes to an ease to her.. i mean i am quite liking the whole sophiscated and not soo gaudy loooking mallika.. i absolutely adored Anju's way of carrying of the creme saree, i feel, Anju is doing a gr8 job carrying on as Mallika, it aint easy being a replacement and trying to fit in...! So Good on Anju for trying to do it soo well..!
And as for being a negative mallika, i highly doubt that... because i really feel there is no basis for mallika as a character to become negative, i hope she remains a positive character!
