"Christiane F" is the first film made by German director Ulrich Edel.The movie looks almost like a documentary what makes it even more disturbing.The acting is excellent-Natja Brunckhorst truly shines as a Christiane,who slowly becomes addicted to heroin.The atmosphere is really gritty and dark,and the film pulls no punches with its depiction of Berlin's drug world.So if you liked "Requiem for a Dream" or "Naked Lunch" give this one a look.My rating:10 out of 10.
