Sati & Parvati both are different forms of Aadi Shakti. It's Natural if we are very attached to one it get difficult to accept the otherone inspite of knowing, both are same. Irrespective of the Chemistry among the actors palying Sati, Parvati & Shivji, the story, characteristic, the circumstances are very different of both these forms. I disagree with Sati's portrayal by the makers. She was a very strong character, I do see Dasha Mahavidyas in Sati, which is her true self. Her time was limited on this Earth, as per the boon given to Daksh by her. On other hand Parvati is milder version, who is with Shivji even today. Want to see her Durgama & Kali form soon.
