I saw an announcement for this movie which included a screenshot: I barely read the synopsis and went, and I'm very glad I did! The black and white images, gradually including shades of grey, are beautiful and captivating, though of course haunting given the movie's theme. It's a story of loneliness, old crimes, and ethnic hatreds fueled by WWII. Worth watching also to learn something about the fate of that part of Europe.
I'm not sure whether someone already mentioned this, but I think it would be nice for viewers to know that Nebel = fog in German.
