Title said enough about the protagonist so I am coming to others things. Story looks inspired from 'Fight club' (Brad Pitt, Edward Norton) of a mentally ill guy whose sub-conscious mind tries to control him, but the movie takes this idea one step ahead. During the first part I was sure about the ending but in middle I really got caught in the suspense and didn't have any clue about the climax. The script writer/ director has done a brilliant effort making no flaws which normally Hindi suspense movies are full of. Movie starts smoothly, with brilliant acting skills shown by Farhan Akhtar. As film progresses, it starts attracting more. Even if you have seen Fight Club and have an idea about the problem, you will also feel the suspense for at least an hour after intermission. So I will suggest you to watch it so as to cheer the new wave Hindi film industry is going into.
