The director of this film seems to have worked hard to give his audience the chills and thrills that they want to see in such a movie, and he succeeds too. They audiences will remain hooked throughout making guesses only to be proved wrong. The film has an unpredictable climax and this makes it a watchable thriller too. However, in midst of all that there are some questions that remain there till the end. In acting, Sonakshi Sinha disappointingly has put up a week show. Akshay Khanna is awesome while Siddharth Malhotra does what he always does. Mandira Bedi has nothing to do in her cameo and the remaining cast is okay. I will go with 9/10 because such movies deserve being made in Bollywood.
