Strange main character
Well, Daniel Brühls Character is strange to me. It is as if beating children at school was something resented in great britain at the time. He always implies how different this was during his time in england.
But children were beaten all over the world for "educative purposes" during these times. This type of punishment was abolished in the UK in the 1980s.
I completely understand that Brühl's character shall be a kind of pioneer. But I would have found it far more believable if his motivation would mainly have been his own experiences with violent education instead of his experiences abroad where he will have seen the same methods.
