I am always reluctant to single out some particular feature of the work of a major filmmaker because it tends inevitably to simplify and reduce the work. But in this book of screenplays by Krzysztof Kieslowski and his co-author, Krzysztof Piesiewicz, it should not be out of place to observe that they have the very rare ability to dramatize their ideas rather than just talking about them. By making their points through the dramatic action of the story they gain the added power of allowing the audience to discover what's really going on rather than being told. They do this with such dazzling skill, you never see the ideas coming and don't realize until much later how profoundly they have reached your heart.
