This absurdist German comedy might also be called “The Strange Little Film.” It takes place almost entirely in the Berlin apartment of a large middle-class family over the course of a lazy Saturday. Catastrophe keeps threatening to strike (household items break with uncanny frequency, a pair of older siblings exhibit signs of incestuous desire), yet nothing remarkable ever happens; likewise, the characters come close to experiencing epiphanies but don’t quite make it. Writer-director Ramon Zürcher presents all this in a rigid, deadpan style; the camera never moves, and everyone speaks in unemotional non sequiturs. This is an acquired taste to be sure, but it’s certainly unique. In German with subtitles.
