She has been a great actress in previous serials. In Mata Ki Chowki, she played the evil sister in law who was just looking to get wealth, and finally turned her husband into the same kind of negative character. She was young and flashy in this drama wearing designer saris, nice makeup, etc.
Now, she plays padma a woman broken by having to marry her sisters husband. She has shades of positive and negative in Jyoti ...
So, she will probably be negative in the other serial. But, I hope at some point she plays a good character - I would like to see this chance for her to show what other roles she can do!
