We bought the full set of Bergerac DVDs recently, and started them a couple of nights ago.
The first scenes seemed a bit 'slow', but the story was strong enough to build up into a good mystery, and we both realised several reasons why - no mobiles, no mention of politics or current nasties, plenty of good photography, and some decent acting from several good names! Everything about it made for a relaxing and rewarding programme.
Seeing that the box set has nine series, I suppose it's proof that they got it about right back then (this is 1981 after all), and new writers could learn a thing or two about what citizens actually want to watch rather than just tick boxes and chuck any old tosh around!
