Even by ITV drama standards this is needlessly tedious and how they managed to drag it out over 4 episodes I will never know. In summary not much happens, the 'twist' is predictable and there are no impactful messages to take away from it. We don't really get to know any of the characters properly and the majority of the programme just seems to focus on Vicky Mclure in a dodgy wig driving around looking gloomy. Shame. There are a few avenues I feel they could have elaborated on or gone down to add intrigue but alas no. What you see is what you get and I wouldn't recommend investing your time in this.
