One of my favourite TV shows as a kid was Hill Street Blues. It used to be on late, probably at 10:30pm on a Wednesday or Thursday night. I remember I used to rush home to see it - at that stage I must've been fifteen or sixteen, but I watched it for several years. My favourite character was undoubtedly one called Mick Belker, played by Bruce Weitz. He was a detective, and used to growl when he was pissed at someone!
I was overjoyed a few years ago when the box set of every single show was released, and one of the things I did when I was convalescing from the stroke was to re-watch them all. Brilliant, very Eighties, was reputed to be set in Chicago but they never gave that away. I think it kicked off a very long career for the writers, though I never saw much of the actors again.
