Never really watched Bulman, never watched any Star Cops, watched Bergerac every week (in fact there is talk of a new version with a younger lead actor), Target was in fact taken off air by the BBC in 1978 as it was too violent.
Bulman was OK, Star Cops had a good theme and some ideas. Bergerac was routine Sunday night viewing as long as NC Public TV ran it, 2 or 3 years I think. Target had a great theme and I liked the action from what I remembered.
Another one they ran was Shoestring. I loved it too.
