Its a Kate Winslet show all the way. And what a mind blowing performance, she just defines acting in this role. There is a definite "Happy Valley" hangover in this series. Happy Valley is a cop raising a grandson single handedly in a area with drug problems and trying to solve abduction of a teenage girl. Here you have Kate Winslet a detective raising a grandson again in a drug infested area and trying to solve lost teenage girls and a dead one. Happy Valley does not have the thriller or suspense element after initial episodes and its more of a emotional rollercoaster which is where this series differs. The suspense and thrill is maintained till the end and I am glad to say unlike other series they don't drag a 2-episode series to 7, they really had content for 7 episodes.
