Not just you mate. All the British broadcasters seem come up with nowadays are quizzes, talent contests and scripted-reality shows of which most (such as The Apprentice) are years past their prime.
I remember when the BBC and Channel 4 used to make lots of great sit-coms like Blackadder, Red Dwarf, Drop The Dead Donkey, Father Ted, Only Fools and Horses, Spaced, Desmond's... plus some decent dramas like Cracker, Auf Wiedersehen Pet, Poirot, Cardiac Arrest... but aside from The Inbetweeners, Misfits and The Thick Of It I haven't really followed any British TV series in recent years and probably the only British TV show I still have series linked is Top Gear!
The vast majority of my television viewing in recent years has been made up of American dramas: The Wire, Deadwood, The Sopranos, Dexter, Rome, Battlestar Galactica, Band of Brothers, House, The West Wing, Justified, The Shield, Breaking Bad, 24, Game of Thrones, The Walking Dead... If there are any British shows as well written as these on TV currently I'd love to hear about them!
