She is a huge let down. Its been 1.5 months and no improvement yet. And she is not a newbie also. She has acted in several short films before.
Even the girl who plays Shreya is a much better actor than her and yes just like you it pisses me off more coz she is paired opposite Shantanu and she ruins his effort and the scene tanks.
More than her lack of expressions , the throw of her voice and the lack of voice modulation affects the scene more I feel and ruins the narration too.
I can't believe MTV India couldn't find a better new face to launch. -_-
P.S - Bindass is launching a new show...the female protagonist there is seen narrating about Mumbai on similar lines like that of Isha's...go and check out her narration you will understand the difference. That girl is also new but she is already so good.
