The film is basically awesome because he takes on a new twist repeatedly. That makes it very exciting, because it then turns ultimately in an unexpected direction. But just at the end I would have wished that after all the cat-and-mouse game there is even an adequate result. But as the end remains very unsatisfactory, what is the whole movie does not do justice. I had the impression that they wanted to come to an end after 2.5 hour film simply because right here it would have been worth it, to have the tension that is held about the film to finally solve and the appropriate person fly up. Therefore I only 4 stars.
