Seriously amazing series with some of the UK's finest actors. Warren Brown and Stephen Graham are mesmerising in it, with a very early promising cameo from Jodie Comer too. Would have been more critically acclaimed if it had been allowed to finish and maybe a 2nd series commissioned. But due to real life events at the time, they sadly pulled the plug on showing the last episode, leaving us the viewers hanging and deeply disappointed. Surely now 10 years on this could be repeated or available to watch including the final episode at least? Would've been a 10* rating had I been able to finish watching the whole series.
