The first episode (http://en.wikipedia.org/wiki/Decalogue_I) is the most poignant of all I think. If you are, like me, teaching your young child how to program this will be both very interesting and heart wrenching to watch. Note that the father's name is Krzysztof, which may refer to either Kieslowski or to Krzysztof Piesiewicz with whom Kieslowski collaborated on the script or both, perhaps hinting that this may be one of the more personal episodes (Kieslowski's father was an engineer, too).
