Das Rätsel

This cerebral and complex film is not the sort of movie you can dip in and out of while you're thinking of something else. The good news is that the essentials of the plot and virtually all the characters are clearly introduced up front. The other news is that it becomes hard work to sort out the teasers, false leads, and almost Aristotelian logic on the way to a wonderfully constructed conclusion. I appreciate films that manage to tie up every loose end, and this one sure did.

Apart from giving great credit to the work translators must endure, the writers managed an intricate, multi-lingual wordplay at one point that -- to me anyway -- was the highlight of the film. So why only seven stars? Because honestly this film was hard for me to follow, but I can easily understand why others might rate it higher.
