I really don't understand why this film did not get any distribution in the US. Maybe it was because we don't really like to share our rides with other people, so the concept would have little meaning--I don't know. I do know that this is an exceptionally interesting movie. The acting is superb, the directing is spot on, and the camera-work is great. The film never resorts to simple answers, allowing every character to have more than one facet. The character of Peter (strikingly played by Ulrich Matthes) is certainly creepy, but the film shows us his social awkwardness and loneliness. We understand the Carolin's anger (Carolin played by the always lovely Anna Brüggemann), but we also see that she has demons of her own to contend with. I really wish more people could see this film. If you don't speak German, the German DVD does have English subtitles. That might help. If you find a copy of this (and you have a multi-region DVD player), by all means, see it.
