Doc Martin - brilliant.
A couple more you may like to investigate (if you haven't already) is New Tricks
- about a trio of retired policemen brought back into the force in order to investigate unsolved cases; Time Team
- a bunch of archaeologists who take on various historical sites with just 3 days to make some kind of sense of them; and Hustle
- a group of highly principled con-artists who pull off the most audacious cons - kindof 20th century Robin Hoods.
There was also an excellent mini-series a while back called Hope Springs
, about a bunch of escaped female ex-cons who wind-up in a run-down Scottish hotel rather than sunning themselves in the Caribbean, which was their original plan.
Oh - not forgetting Wild at Heart
- the story of an English vet (and family) and a game reserve in Africa for endangered species.
Hopefully Rapidshare, Youtube, FilesTube or something similar will supply.
All of the above have either ended or are on their last series - usually due to having run out of new ideas for scripts, or have simply gone stale after long runs.
Hope there's something there you like.
