Two of my all time favorite tvs shows were House of Cards and Glittering Prizes. Virtually no one has heard of the second one.
Also liked Prime Suspect. Eastenders, fine.
Have wandered away from tv watching for more than a decade. Well, really, since I went back to school in the eighties and got away from being glued to it. I feel a fit of it coming on again soon though.
