...when Jimi points out that the War (WWII) was fought to make everybody free from racism/xenophobia and made a guy apologize for a racist comment he made to Lulu.
The acting was good, and both protagonists were attractive and fairly believable in their roles. I liked the controlling mother, though showing the father's self-castration was a bit over-the-top.
In general, I agree with the first poster that this movie was weird, and I was actually nauseous from the gunfire, blood, fight scenes, and views of hypodermic needles by the end of the movie.
Also, as an American, I was hoping to see a German movie, and there was all this English dialogue, American music, and American cars in the movie, which spoiled the experience for me.
