I like the movie. I enjoy the DVD.
The movie does an excellent work in setting the atmosphere, ambience, and the tone of The Crimson Rivers. I rate these qualities over the story. Watch it. I believe you will experience what I feel. I could relate to the coldness, eccentricity, foreigness, suspense, and many dark emotions that the movie expresses.
I like the story too. I am a sucker for stories that developed from few isolate incidents to a grandeur scheme involved almost everyone. From the excellent bonus interview that is included in the DVD, I believe the book would be a much better interpretation of the story. Although, I have to argue that the interviewee are not too modest nor subtle.
Almost a classic, but I definitely cannot say it is... just a good movie that you would discuss quite a bit after watching it.
