I watched "Russia 1985–1999: TraumaZone - What It Felt Like to Live Through The Collapse of Communism and Democracy" (7 episode documentary series) last year and can highly recommend it. It's not like any documentary I'd ever seen, there is no narration, very little "story" exactly, it's mostly a collection of footage spliced together (I believe it was all/mostly BBC footage, a lot of it seemed like b-roll-type stuff).

I found it absolutely fascinating. After the first episode I didn't think I'd watch anymore of it since it's very odd (how it's presented IMHO) but it kept drawing me back in.
