I have only watched series 2. The plots are interesting enough - but really, they are almost beside the point. Yes, there are social issues, there are personal issues, there is some suspense, some romance and not hard to figure out plot twists. Also there is this big question. What always baffles non-British is why do British police (in TV series) so often go into knowingly risky, if not potentially fatal situations, unarmed and not backed up. It happens time and time again. It happens here. It happens in other British police, crime, legal series.
So, what is it that makes The Vice - so good? What impressed me was the very high quality of the actors. Their ongoing performances are stellar. There is a constant upward moving arc in character development, in their subtleties, and in the connections they make with their audience. Its ensemble casting at its best. Ken Stott is a master in every way. David Harewood and Caroline Catz are equally intriguing in their roles. The secondary characters are invariably terrific. Highly recommended.
