One thing you're promised from Japanese films is their devotion to various forms of music, be it Western Classical music, ballet, or Alternative Rock. In that respect, the recently watched Confessions might easily join ranks with Love Exposure. It has a strange yet extremely effective combination of Bach's Concerto no.5 and Last Flowers (Radiohead), that's put to deliriously orchestrated melodrama as LE's own eclectic combination of Ravel's Ballet and Beethoven's 7th Symphony. Significant that both films share disturbing themes (from Incest to oedipal rex), once again emphasizing & underlining the scope of WCM (be it Bach or Beethoven) in background compositions. And Japanese films open up such operatic opulence with relative ease. It's to do with the tradition that they carried on from old dance-(melo)drama routines.
Tchaikovsky - Swan Lake (heightened by the fact I saw "Of Gods and Men", more so than Black Swaaan anyway!) The acknowledgement of abyss towards the latter stages makes for a tremendous effect in "The Last Supper" scene..
