I'm only sorry that the director didn't make more feature-length films. I absolutely loved this. The plot is well laid out - it explores the reminiscences of a daughter who is coming to terms with her mother's death. The acting is first rate, particularly from the two female leads. It is thought-provoking in a very British way which is unfortunately lacking in many emerging UK films. The film incorporates lingering shots of scenery in Edinburgh and Orkney. It is careful and measured but in a way that, for me, does not detract from the pace of the film.
It certainly takes a mature outlook and some patience to enjoy the film. Perhaps it is one that you either love or hate.
