You know guys, its actually very difficult to judge how an actor is these days.
A lot of acting depends on writing. Take Zain for example, he was so so good in Naamkarann. But he wasn't great in IB, why? Because they made him a magician
Even one of favs, Jennifer W. was way better in Beyhadh than in BP.
Kunal was good in IB, but most of the time stagnant in DBO. Because they completely switched his character.
So, I really don't know whether the actress playing Chanda is good or not. I think the writing of the character is really horrible. Except the two emotional scenes with her kids, she is super duper annoying.
The makers of this show put a lot of effort into Jahnvi's character, but I think now that the show is on air, they should write other characters well too. Specially Kabir's, because most ppl are watching either for Shrenu or Zain or both.
