Lars Becker, the director of LANDGANG FÜR RINGO, has written some great crime novels, so he knows a thing or two about writing a story with an interesting and clever plot. But the best part of this movie is its atmosphere: Since it's christmas time and snowing even ugly, graffitti-covered buildings in the suburbs of Hamburg appear beautiful. The music is wonderful as well and evokes strange (and hard to desribe) emotions. "I got the vocab", for example, sounds aggressive and soothing at the same time.
Add to this some great acting and a very dry sense of humour (the scene with the pitbull in the elevator is priceless!) and you have a unique and wonderful movie. The other films of Lars Becker ain't too shabby either!
