I watched it only because it was on TV, and there was not anything better to watch. This is one of those kinds of movies you have to be from the place where they were made in order to like them. I am not from Scotland, so I did not like this movie, but the main reason was the acting, which is mostly poor, and sometimes over-the-top. Add to that that the story is unbelievable. The mad policeman can do whatever he wants, and nobody does anything to stop him, either physically or legally. When he speaks, everybody just stands there and listens. Come on! And the mutual stabbing in the end is laughable. Well, there is a reason why I had never heard of this film before.
