Ken Stott as Rebus had his foibles and issues and certainly was convincing as that character, and here he plays basically the same 'type'. This is neither original nor terribly written, but it feels and looks 'tired', as in: we've seen this before. The acting by most who appear is generally top-notch, but the dark and graphic nature of the main theme of 'vice' is just a bit much. Do not watch this before bedtime. I admit that the subject matter and giving so much airtime to deviants and abusers makes me cringe and does not constitute 'entertainment' for me. Although crime and police dramas are often really enthralling and can stretch your imagination at times, this particular series was just a bit too gritty for my tastes. It's not badly made or overly violent, but it totally lacks any light moments or humour. And the relationships all come across as fractured. Not a fun time.
