Any point in history and genre.
For me, it’s Stalker by Tarkovsky. I hadn’t seen it before, so I watched it twice. Once on YouTube and then again with the nicest file I could find. I loved it so much. Solaris is the only other one of his I’ve watched, so I’ve got all of them downloaded and ready to watch now. (thank our lord, rutracker)
Strongly agree with your whole comment. I wish it followed through more with the opposition to ethnically cleansing animal people, but maybe they’ll get more into that in part 2 (I haven’t watched/read the source material).
