This is a good movie, with a well acting female lead as the newspaper copy-girl Patricia who dreams of becoming a reporter and stumbles upon clues on a child murder in the area. However it is not great, and the thick Glasgow accent of all involved makes it even less accessible to non English audiences.
I don't know why they called it a series, either, as it is really a two parter film. Maybe they intended to continue it with the adventures of this tiny girl in this tiny community of uber-Catholic tiny minded people, but what would have been the point?
Bottom line: a nice watch, with convincing acting and script, some thrills and a true glimpse of Glasgow in the 70-80's. Subtitles don't hurt, either. Peter Capaldi plays in this one, as a secondary character.
