Bjelogrlic really out-done himself with this movie. Based on the book "Vinca case" and a real event that occured less than a century ago, the plot captures an intense story of both trying to build an atomic bomb in ex Yugoslavia and curing the scientists from all the radiation caused by it.
Some of the scenes were to agonizing to watch, so it is not a movie for everyone. The protagonist has a dual personality, where we both understand (pitty) him and hate him and blame him for all the mess. Nevertheless it leads you through happiness, pain, anger, sadness, disbelief and many other emotions but for sure will not leave you numb.
I think that this story of the first bone marrow transplant was an important one to be told to honour Georges Mathé and his astonishing work that helped many. Apart from that I really liked the idea of the subtitle "Chain reaction" which fluctuated through the film and practically explains The butterfly effect and the overall consequence of every small action.
Some of the scenes that show kindness and joy in people in the hardest situations made the whole movie so special.
Overall the acting is impeccable, and the plot, as I mentioned, is so touching and one of the best pieces I have seen for a long time.
