Sati and Parvati are two different personalities. They are Adishakthi alright but they are two distinct personalities. Their upbringing is different. Moreover Mouni Roy who played Sati is an established actress while Sonarika is new to the TV industry and also shes just 18 whos playing such a larger than life character. It will take time for her to step into Parvati's shoes. In fact she is improving with each episode.
I have not followed Sati ( didnt watch DKDM then...wasnt aware of it ). I started watching because my friend recommended me to watch this show and I started watching when parvati was a 5 year old living in dadhichi's ashram. So I cant compare them acting wise.
The chemistry is good between Mohit and Sonarika. I dont see why such an issue abt it. After all its a mythological show. Much is left to the viewers' imagination. Parvati is shy, poised and calm...she doesnt have an ego...I think Sati had a bit of ego ( must have got it from her father ) and maybe more forthcoming unlike Parvati who is a little shy. And we have yet to watch the upcoming episodes. So we shouldnt just jump to conclusions abt Moharika. Also depends on who calls the shots at the scene.
Anyway I am enjoying every bit of the show. They way Shiv looks at Parvati, the way he feels her pain, the way he agrees to all her decisions,..awww that is love...pure love. He is Bholenath:) The precap is good. The way he embraces her...his eyes speak everything. And of course Parvati will melt in his arms all shy:) Shyness is a gehna of a newly wed bride:)
