Well here is a detailed review.

Direction was average. Editing was poor. Bgm again is poor. Story is good tries to keep you on the edge but you still fast forward it at many places just because of poor editing. Character development of some characters should have been thorough. You can't just gave a sharp turn to a story without proper braking. Its a story not a race. Acting wise the DSP falls short. SP guy is good he looks like a tough cop. Again acting could've been a lot better. Could've been a great movie only if more homework was done. Like the behaviour of killers serial killers I mean. 6 on 10 for me.
