Nobody is indispensable in this world. This is law of nature, with change you find new vision. Why everybody is crying for Shilpa when she gives damn to her fans. We love Dr.Ridhima, the character, not Shilpa Anand. Initially Shilpa was expressionless. Gradually with DMG she started improving. Initially her looks were not good but slowly slowly she started picking. Same thing can happen to new Ridhima also. We have seen her with curely hair and get up suitable for her serial. May be for DMG her get up will be changed matching to Dr.Ridhima and may be she looks better than Shilpa.
I think rather than making fuss over changed Ridhima, we have to show to Shilpa that if she does not care for her fans, so do we. Show must go on. I feel what execuses she has given are not true. She left this serial becaz her BF did not approve of her closeness with Karan and may be he was feeling insecure becaz everybody was looking Karan and Shilpa as best Jodi so he insisted her to leave this show otherwise................. So she had to opt for this.
