Film "Amok" Psychological thriller

It is a film based on real facts. Concerned about the writer, he published a book about the murder. Throughout the film a coptry to konw whether he is joking on a murderer or a victim of ambition. In my opinion this film is heavy but very interesting. He is touched a lot of threads but still keeps the viewer in uncertainty whether the hero is a killer. I think they will be interested in people who like this type of crime drama. I divided ten movies into 7/10 because I had too many different themes and I was in the whole movie.
