Watched this with great anticipation but seriously disappointed. Do not like the actor playing male lead ( Sam Riley?), do not find him credible as a very senior detective. I get seriously irritated by the way he whispers everything, not bceause I can't hear it, I can, but because nobody talks like that, all husky whispers. I can hear the other actors ok. I think I was expecting an older, more rugged looking actor as the lead, maybe I have got an ideal picture in my mind, someone like Ken Stott as Rebus perhaps. Sam Riley just looks too young, and not credible as part of this underground old boys network that appeared in this week's episode.
