Law and Order UK was pretty good, although the stories seemed to be adapted from the original American versions and that often didn't make much sense in the context of a quite distinct culture and different police and criminal law systems. It's good drama, well produced, with an impressive cast.
My Family looks like a fairly unimaginative copy of something American. It's about a horrible dentist, his horrible family and his horrible colleagues and his horrible neighbours. It was horrible and ran for what seemed like forever, probably because despite everything it had a great cast.
