The story itself is confusing but it is a necessary for thriller. The suspense was very unique. I mean, there is very few movie has been made movie on a identical twin character.
Now "Mrunal Thakur" is a big disappointment. From beginning her act looks like she is not fulfilling the expression required. Although, it was a challenging role. The only person I can think of is "Tabu" who could have taken this movie in 8.5 rating. Anyway she tried her best because it was her debut.
Aditya Roy kapur and Ronit Roy was really great in acting. That is the reason it was not looking really bad. Apart from it, there were certain side character didn't perform well. Casting choice and Direction was a bit lacking.
A good job for "Aditya Roy Kapur" since it was challenging role for him. Hope he gets more credit. He has talent but he doesn't get good stories most of time.
