Rating: Green - a suspense thriller very different from the usual stuff. The movie is unique in the way that instead of taking the story forward it takes the story backward. Also it has a non-linear structure. The setting continuously shifts between the past and the present. We already know what has happened. The movie is about how and why it happened. Must watch!
