From the trailers and songs , most of the movie is sorta guessed at. A sad / tragic love story , the question remains it has been handled well by the scriptwriters , the director etc.
The answer is a resounding yes. This is Mohit Suri's forte and he has elicited a fantastic performance from Emraan , Vidya. In particular this is Emraan's movie , his eyes speak volumes in his scenes.
The music is well placed.
The characters are not black or white , but grey, with their self motivations.
It's worth the money of the ticket. Go for it ...
