Certainly one of the most challenging films I have watched in a long time. Bizarre and confusing, but also beautiful, elegant and circular. The uneasy tension it builds in the first two acts is pierced in the third, and the story is re-told in the mental unravelling of the main character. Or is it? Don’t watch this unless you’re willing to pay close attention for the whole two-and-a-bit hours, otherwise you’ll just go “huh?”
