I feel that Sid is a very good actor and could have done wonders with Ranveer, if the character had not been so mercilessly butchered by the creatives. I think the Ranveer I liked best was the grey one who loved his family but was a bit shady. I think the way they developed him with Raashi was great and also with Rano. Than I don't know what happened and they just killed his character with all the knee jerk changes.
I think he should come back as negative and go back to his old way of trying to take over Walia industries and he should be kept away from leaky tap. I would love to see him bond with his daughter. It would be great if they showed a track where he slowly develops his humanity back maybe by wanting to be better for his daughter.
Also for the time being want him to be away from both Rano and Raashi.
