As a retired DCI myself, having joined the Police in the early 70's, I have to say this series really does touch a nerve. Full of sexism, racism, excess drinking, macho characters, this is not that far off exactly "how it was". Of course there is some licence, but the core is on the money. Glenister portrays the basically sound, well meaning but firey DCI Hunt to perfection. Good supporting cast too. The stories are not far from reality, the scenes are well researched and the whole series is a cameo of Manchester/NW England in the late 60's & early 70's. Scruffy, unkempt streets and factories, a good deal of deference to the Police by most, even the baddies. Plenty of action. Storyline is not that straightforward unless you have seen the series from episode one. Highly recommended, enjoyable, but very non-PC, watching.
