These days the trailer of the movies shows you the entire movie. The same happens with the case. Till the interval you know whats going to happen.I mean according to the trailer both the protagonists will tell their side of the story. You are then left to watch and keep guessing the murderer. Dont worry Ill not ruin the fun. Ive given 3 stars because of the ending. Its rather interesting and leaves you with a smile when you come out of the theatre. I find the background score little weak because it fails to keep your eyes and ears glued to the mystery spun around the characters.
