Crossroads, Eldorado...
How far back are we going in time and memory? I loved 'Rawhide' when I was a kid: "Ride 'em, rope 'em, brand 'em... " a young 'Rowdy Yates' was pretty lustworthy then, too.
Loads of good series, most of those I prefer are listed. Hustle, Spooks, The Sopranos, Desperate Housewives, Midsomer Murders, Morse, The Blue Planet, Planet Earth; almost any recent series on wild life, landscape, art (remember Sister Wendy?), history, discovery, anything with Louis Theroux, Dan Cruickshank, Attenborough; the World at War (grim, as one would imagine, but full of astounding photography); both the CSIs, The Shield, Law & Order, Hill Street Blues (THE seminally-different cop show on which so many are now based); Miss Marple with Joan Hickson, Poirot with David Suchet; the Antiques Roadshow, Flog It!, and Bargain Hunt with Tim Wonnacott, rather than the increasingly oleaginous and unctuous David Dickinson. Dalziell & Pascoe, Taggart (with or without the late M. McManus)... blimey, this is getting silly...
