Oooo, another vote for Northern Exposure! And Clavdivs (I Claudius) may be gory, but it's just fantastic - Derik Jacobi is totally fab, and as for Brian Blessed as Augustus and the wonderful Sian Phillips - just wonderful TV!
Morse and Lewis are getting repeated on ITV3 currently - really enjoying them. And Wycliffe. Recently was laid up in London with diverticulitis, sleeping on the floor at DD's (She did very kindly offer me her bed, but seeing as we ended up staying 2 weeks instead of the single week planned I felt it would be too mean to take her and SiL up on the kind offer), and really enjoyed having a detective fest of stuff I'd missed first time around. Kept me sane between trips to the loo (sorry TMI!). Frost is quite good too.
