We advise you, when thinking about this movie, to think of it as three separate stories in which nothing is connected. This is one of the movies that are popular only to minor groups, but actually have good way to show that even though people are not connected at any pint, that can have almost same issues, and can help each other, but there was no such coincidence, so they can meet. As we have mentioned, there are three separate stories of characters that are doing their daily duties. There is no big connection of characters with the audience. You are only there to have a slight glimpse on their life, see it for a while, and that is all. You will get the feeling that movie is quite boring, as you are constantly switched between those stories, but for someone who likes complex stories, this will not be a problem at all. Each of these three stories could be a movie on its own, but directors actually wanted to make something different and put new frontier in the movie production. Unfortunately, their work has not been accepted as they would like it, and that is why there will not be soon movies with similar ideas.
