The first half of the film was quite thrilling and the second half till the interrogation of the doctor then when the doctor tells that he isn't the actual culprit,I could assume that one of the friends of the heroine would be the villain.It is a okay movie but when the actual villain was about to get revealed it should have been a more thrilling scene.But hats off to the cinematography and the direction.The screenplay should have been a little more interesting and thrilling.Over all rating 7.5/10.
