One can see the origins of modern British crime-series in this. A similar approach is also to be found, although less overt, in the more recent "Waking the Dead" and "Silent Witness" where an over-worked, dedicated team go all out to solve their crimes against a hard, ugly underworld on the one hand and mindless, stupid and often self-seeking bureaucracy on the other. "The Chief" is a good, well-designed and absorbing series. The plots are good, and they are well-developed with a cast totally in control of their various characters.
It does state that it deals as much with the politics of government as with crime, and that is true, but one also finds that each cast-member has his or her own agenda - often a very large axe to grind. The criminals are not always simply bad people - they are reacting to a big, unfriendly, uncaring world. The police have their issues too. No one seems just to go to work to make a living and leave the world a slightly better place. Most seem to have burning issues of their own which are worked out in the work place.
If you are happy with a bit more depth to your police-series, then you will enjoy this one. It is thought-provoking within its ambit, it is well-put together and altogether, very entertaining.
