It is a very good and well crafted film.
Extremely slow moving but with sinister overtones bubbling along just under the surface, It kept your attention, wondering what was going to happen next. As the film inexorably built up to its seemingly predictable climax, things started to make sense. It is the type of film that I enjoyed discussing after it had finished, as it was thought provoking and very dark in parts.
Well worth watching if you enjoy slow but beautifully crafted movies.
