I guess with DR gone, the serial needed someone to play the villain and vedika it is. look at how they changed her character. when the serial started she was not potrayed in this manner at all. resenting the fact that vasu was her step sister. infact she supported her all the way. they change the nature of the characters to move the story line so drastically sometimes that it becomes unbelieveable. it tends to lose its credibility to hold your interest.
Frankly that is how i feel and i have lost interest in such a powerful serial that was so promising when it started.
Look at how they changed DR right at the end. suddenly as if he had an epiphany.
