Watched the movie today. The screenplay is somehow simple: there are just two main questions whether the message will be delivered in time and action will be cancelled (vaguely said in order not to spoil anything) and whether the brother will be met. So, no other twists for me there... But an incredible cameraman work keeps interest of a viewer till the end. The gluing together of shots is so smooth that there persists an illusion that the movie is made in one shot. Also, the music - it sound with the precise scene mood at the right time which amplifies watching experience. Neverrminding the screenplay and my rating of 6 stars, it certainly worth watching at least one time.
