Jennifer and Harshad are such precise actors, their expressions are easy to read. Same for the actors playing Anjana, and to an extent Mahi, Madhu, Noor, Pooja.
I know I'll get joote chappal here, but I think the actors playing Sakshi, Papa Hooda, Yash and Arjun are not very precise: you don't know what they're thinking: try and get a screen grab and it is impossible to tell. This could be because the director doesn't want to give things away, or because these are just not very good actors ( I've never seen them before).
So Sakshi manages to look constipated instead of guilty ( we can guess she's guilty because she's paying others off), but we can't figure out her motives behind hiding things: does she want to hurt Adi or save him from being hurt?
