If you liked Happy Valley, you need to watch this TV series. Both were written by Sally Wainwright, and the dialogue is much better than most U.S. cop shows. She took a cue from playwright Barrie Keeffe, who "was an early influence – he never uses commas, just full stops… just hits of language. Like David Mamet it feels fresh and very alive and how people really speak."
I also love that the main characters are women - flawed, yes - but real and admirable in their resilience. Had to binge watch the 1st season, it was so good.! Looking forward to more of this.
