Myself I just watch whatever I find on Netflix when I have time. Mostly old re-runs I'm sure, and mostly comedies, or horror movies. Red Dwarf, the Catherine Tate Show, Fawlty Towers, Black Adder, Doctor Who and Torchwood. I don't usually do a lot of TV watching, so my repertoire is limited.
One of my favorite horror movies of all time was, I believe, a British film called The Expelled. It took place in England at least. It was this father and daughter and a few staff trapped in a school with murderous children in hoodies. At first you thought they were just delinquents, but by the end of the movie, you couldn't tell if they were supernatural or not. They would just appear out of nowhere, often in groups, and you never saw any faces. It was great!
British TV is pretty superior to everything we have here though.
