I'll begrudgingly give it one more try.
Diane Kruger makes a great actress for this series. Her character is supposed to have Asperger syndrome,but anybody who has ever been to Germany,known or married a German,would recognize her behavior as typical German behavior(which Diane Kruger happens to be by the way). I've lived in Germany(Berlin) for almost 3 years & was married to a German,so I believe that I can safely make this observation.
