Saw this in a theatre when it released in 2010. Was discussing with my friends how most of the Bollywood psychological drama/thrillers r basically not at all original. This name came up n when I told my friends about this film being heavily borrowed from Adam Green's Spiral, I thought about writing a review of it. Inspite of it being borrowed, this film is a good one time watch n it is heavily saved by Farhan Akhtar. There's something weird about the lead character in Karthik calling Karthik played awesomely by Farhan. It's easy to feel sorry for him. Farhan gave a memorable performance in the role of a deeply disturbed and secretive individual. Much better than Moore from Spiral. Fellas who havent seen Spiral will definitely enjoy the twist. This film is more of a psychological drama.
