typewriters banging away, smoking in the office, saloon bars that have the blues playing in the background.....
When I re-watched the Season One DVD last year I was surprised how the show made the right wing militarist policeman, Lt Hunter, so cartoonish/bufoonish and quite beyond the pale. If I remember he was made more human as the series progressed thereby diluting the quite explicit liberal stance. In fact, the whole programme became more mainstream as the ratings grew...although I think that comment could apply to a few other programmes as well...............
