then it's naked lunch I guess
didn't want to like it, but was enjoyable
can't really think of any particularly good documentaries on anything from this period, though I've seen quite a few. I generally find most things by 'big name' historians like David Starkey dull and worth avoiding.
Marketa Lazarova for a similar thing - incredible film, with a really strange narrative structure. apparently voted the best Czech film of all time by Czech film critics or something. Also the Valley of the Bees, which is directed by the same guy. Shadows of Forgotten Ancestors is also amazing (no idea when it's set though - it feels medieval but it could be set up to the early 20th century really).
then from non-eastern Europe you've got Seventh Seal and Virgin Spring, the films of Carl Theodore Dreyer - Passion of Jean of Arc in particular, as well as Day of Wrath (though I think this is far from his best) . Aguirre, Wrath of God is probably set about the right time as well, if you've not seen that.
Fifteenth century Russia. Lots of brutality and painting.
