The producers of this movie stressed that this movie was not strictly based on the book by Peter R. de Vries, the crime reporter. This book is (claimed to be) an accurate account of what the planning, kidnapping and aftermath actually was like. One of the greatest features of that book is the planning stage, which was incredibly meticulous and exciting.
The producers decided to go their own way, but made a critical error. They assume that people know the story, and subsequently leave out key parts of the narrative. This leaves the audience guessing at times what is actually happening. The planning stage is almost completely skipped with the kidnapping taking place in the first 10 minutes of the movie. A bit later there is a scene where the kidnappers are waiting for a ransom money transfer but this goes awry. The problem is that it is not explained that this is a ransom transfer attempt, and uninformed people that are not familiar with the actual kidnapping do not have a clue what is going on.
So the producers decide to NOT base the movie on the book, but trust that the plot is explained by the knowledge people have of the book. It's easy to see that this will not work, and so it doesn't.
Pacing is also a problem as scenes seem to drag on forever and overall atmosphere is very negative and pressing. It seems like there is a fire burning underneath the movie and pressure is building, but it is never released soon enough to be a pay off for the audience.
Acting is quite good, but the script and wooden dialogue aren't doing the actors much favor. Hauer as Heineken is a good fit, as is the main character who is a dead ringer for Willem Holleeder.
It was a mistake to make a movie about a topic so famous that (almost) everyone knows the complete story and subsequently twist the story in the extent that they did. I almost wish Peter R. de Vries will go through with a script more strictly based on his book.
