First of all, never pass up an opportunity to watch a series from the pen of Sally Wainwright. Secondly, be similarly alert to watch performances by Suranne Jones. Now, add a stellar cast of the likes of Peter Davison, Gemma Redgrave and Siobhan Finneran and you’ve struck gold. This has a story with heart and depth with performances by the best. I give this series a 9 (superb) out of 10. [Crime Drama]
