The second of Krzysztof Kieslowski's "Three Colors" trilogy, White (for Equality), is, as I remember it, an uneasy attempt at an anti-romantic comedy about a man's determination to get revenge on his ex-wife.

I don't remember much about it other than that it might have been at least border-line misogynistic and that Zbigniew Preisner's score was one of my favorites.

It's essentially one very reflective, lonely, beautiful theme arranged for a minimum of instruments, with the flute most often the featured voice.
