I endured all episodes of this dire offering from the BBC. One and a half episodes in and I really didn't care what happened to any of the two dimensional characters, by episode three I was skip watching just to get to the end. The flimsy storyline revolves around the lengths to which the female protagonist will go to get revenge on the man who killed her brother many years previously; the whys and wherefores of which are never fully explained. She is a teacher, so supposedly intelligent; but her actions become increasingly ridiculous as she twitters, cries copious amounts of tears into copious amounts of wine and lurches from one unbelievable situation to the next whilst dragging her equally stupid friend along for the ride. By a strange coincidence her husband; also a teacher; teaches the son the man and there seems to be some kind of never goes anywhere subplot involving the two of them. And then we are treated to an ending that is so bad it is laughable. The whole thing is made worse by the poor acting, the dire dialogue and the lack of any resolution or explanation of the subplots. This series falls well short of taut thriller status. If you want a good "revenge stalking" thriller try Red Road instead.
