This film popped up in my recommendations recently and I recently watched it. Despite quality issues I think it’s one of the most powerful and disturbing war films I’ve seen. It incorporates some surrealist aspects, which makes me think of it as a sort of Soviet Apocalypse Now for the Eastern Front in WW2 (set during the German occupation of the Byelorussian SSR). In a way it’s the closest thing to a two hour long nightmare, but I recommend it if you are in the right mindset to endure that.
