I won't give away the "key" -- that's for the viewer to discover -- but until I figured it out for myself, about 2/3 of the way through, I was so exasperated by this movie that I was tempted to just give up on it and quit. I thought it was incoherent and disjointed, and actually got peeved since I thought it was screwing with me.
But THEN... I figured out who/what the young officer in white, and the various appearances of the attractive woman, represented... and my whole experience changed. By the end of the movie, I was devastated. The lingering final image and text -- and the song sung over it -- left me trembling and weeping. The whole thing haunted me for days, then weeks, afterward.
I intend to watch it again from the beginning, now that I know what it's about. But I am waiting a bit, since I still haven't recovered from that first experience.
This is a very different kind of movie. It's NOT a straight story/narrative, and expecting such will just leave you frustrated. Mikhalkov is a sort of poet, who has used seemingly unconnected images to evoke feelings and impressions. He uses visual/emotional images to conceal deep realities of history. And, for this viewer at least, realities of humanity in general. For though the movie is concerned with 20th-century Russia/USSR, it speaks to me, as an American in 2022, of a more general truth, one we should all take to heart as our own glittering Western consumer culture heads for collapse: Concealed beneath superficially beautiful things (and hoo-boy, are the "in-color" parts of this movie a sensual feast for the eyes!) can lie the ugliest horrors of which humans are capable.
