Go and watch it, This is very much interesting for those people who did not watch the trailer and had no idea about twins in the movie.
I, myself, kept thinking that makers are showing three different stories/stages of a person's life until the hospital seen arrives which reveals they are twin.
The climax is of a different level, I watched the movie and i liked it and i keep thinking about the ending of the movie so much that I am now ending up here writing few words about the movie.
Very good performance by everyone, especially Arya.
