it be by far the most definitive film on the police force which i have see . although not direct by ram gopal varma and it have all the element of an rgv film . dead straight dialogue and blunt treatment of the subject and brilliant direction and and superb performance ( even by those with little job to do in the movie ) . the chemistry between nana and the don and even if they be professional rival and be amaze . and so be the small event like an insider not give information to imtiaz even while he be be bash up in the locker and but only to nana when he be out . the change in work condition with the change of the senior be dealt wonderfully . the first half keep one absolutely engross and move like a documentary with nana act like a mentor to jatin explain to him the intricacy and philosophy of the work . overall one of the most brilliant film on cop in indian cinema . definitely not to be miss .
