Much thanks for your list Mik!!
Ferom the ones you listed I've only seen 13, which are imo all essential. The problem here in Germany is availability also (as I don't speak russian I need subtitles).
But the films I want to see the most are the early films by Paradjanov (e.g. Flower on the Stone, Ukrainian Raphsody, The first Lad) . The excerpts I've seen from this were absolutely breathtaking to me.
Could you maybe write something about those?
