Shah Rukh Khan is back and how!I truly missed his 'acting' since long. He proves he is a great actor in the scenes where Gaurav is heart- broken and cries his heart out when he sees the true face of Aryan Khanna. Another scene where he excels is the one where Aryan imitated Gaurav, that's a classic transformation. The vfx and action sequences are of very high standard. Maneesh Sharma's direction was top notch. His camera captures the middle class, small town life well. The first twenty minutes give you a full Delhi flavor. His choice of locations of the capital is quite impressive. The first half is a little slow but important to suck you into this story. The real deal of the thriller is of course the second half which is pacy but weak on the script front. All-in-all a great package all together. One shouldn't miss this SRK film.
