I have a few:
CSI (original & Miami)
NCIS (original and NoLa)
The Voice
some news shows
and my guilty pleasure - General Hospital
70s Britcoms
We haven't had a TV in well over a decade. There have been a lot of shows I enjoyed. Some of the ones that come to mind are:
WKRP in Cincinnati, Firefly, Barney Miller, Babylon 5, Farscape, Red Dwarf, ...
Most British Comedies for me as well - just started watching re-runs of Allo Allo, although not one of the funnier ones.
Fawlty Towers
Mr Bean
Come to mind though
