This is such a masterpiece, i just saw this movie today and this is just about conducting an exam for selecting an employee for company. Once the movie started, it little bit boring but after 5 to 10 minutes, I bet it, u feel very connected to this movie. 80 minutes to find a question not an answer. I think no one can get an answer before last 10 minutes of movie. For some people(who loves to get some extra) the climax may not be able to satisfy their feeling, but trust me ENDING PART IS AMAZING.......... I still very confused that why this has just less than 7 on IMDB.......... For me, this movie deserves 8 or 8.5....... Superb writing, stunning screenplay and magnificent acting.
