I loved the Three Colours trilogy by Krzysztof Kieślowski, including Trzy kolory. Biały
http://en.wikipedia.org/wiki/Three_Colours
I saw them well over a decade ago, though, when they came out, so I can't really remember the details of them.
I do recall though that I particularly liked Trois Couleurs: Bleu. I was really moved by the music, the mood of which was also blue, and I loved the visual blue theme that ran through the movie, the blue water of the swimming pool, the blue crystals of a chandelier or wind chime or something. The theme bleu very subtley ran through every aspect of the movie, the music, the mood, the details in the set. Beautifully done.
