This takes an absolute age to get going. Constantly flashing backwards and forwards. Bizarrely, some of the flash backs have no bearing on the storyline whatsoever so I can only guess they were added as filler, and that's one thing this season really does not need. The whole story could have been told in a couple of hours maximum. Whoever wrote it needs to take a lesson from Strike, or Endeavour. There's nothing wrong with telling a story slowly but it needs to pull the viewer in and at least hint at some kind of direction. The actors here are out of the top drawer but have so little to work with you feel sorry for them. The streamers have come up with some great crime shows, like Slow Horses, but I'm guessing this isn't going to make it to season 2..
