Query: Poor rendition of a great novel

The Man from Beijing is an excellent murder mystery. Unfortunately, the German production company mangled the story to the point that it is a poor rendition of the original book. The cast turned in a mediocre performance as well. Amazon instant video didn't help matters with the audio and video out of sync for all but the last five minutes of the movie. My wife and I thoroughly enjoyed the book and were very disappointed with the movie.
