Yonks ago this flick impressed me deeply. It's closer to a music video than narrative film, though drama there is. The sound is immensely important in allowing the viewer to feel the passage of time, while the camera captures almost-stills.
The obvious theme is domination and submission, but also light and dark, stillness and motion, freedom and constraint. A beautiful short essay in yin and yang, with a brilliant sound track and compelling visual composition. The superficially sexy theme seemed less erotic than stylish, though it scores on both counts.
I remember this as one of the most poised and elegant moments of cinema.
