I loved the natural flawless acting of Sai & Dq (As i'm completely done with bollywood actor's over acting). I have no clue why some people rated this movie so low. Its a masterpiece, i came across such a movie after so long.The story build up is really commendable, suspence was top notch too. Its first time ever, that i have appreciated action scenes of a movie, was totally in awe. I guess we should start appreciating such realistic movies while avoiding the overdramatic movie sequences. I believe Its not just a one time watch but an experience to cherish forever for a moviejunkie.Overall great movie, tremendous acting & direction.
