I saw this ages ago, and didn’t get round to posting this short review. Its probably out on DVD by now.
It’s not Lady Macbeth in the Shakespearean vein, but instead the film is based on the novella and opera Lady Macbeth of the Mtsensk District. A young woman is married off to an older man, who manipulates and humiliates her and when she can, she takes her revenge. It’s a very dark movie, both visually and in terms of story.
