I found it by chance in my library. I nearly forgot it, since the time I taped it off from French ARTE channel. Yes, you can compare it with a Marty Scorcese - MEAN STREETS - like tale. Petty hoodlums in Germany, mostly from immigrant descent: Turkish, Serbian, most of them brutal, violent volks. It is not in the Quentin Tarantino style either, it refuses to copy the new fashion of this period, trying to imitate Tarantino's way of story telling or filming at all costs. It sounds very realistic, the acting more real than life. It grabs your attention and the characters, despite what they are, remain poignant, gripping. Excellent social crime film.
