Dexter is pretty good as is House. Though there pretty common and already established. I'm not sure where you are from (FLorida or switzerland or both?) but if you get the BBC I recomend seeing wht they have on, probably the best quality TV in the world.
Really? It was not that good when I saw it plus Mr. Brand is a bit of an idiot (poor Andrew Sachs)
Also Mock the Week and Never Mind the Buzzcocks are probably the funniest things on TV at the moment. Frankie Boyle is a legend and the Donny Tourette episode of Buzzcocks is probably the mist hilarious thing I've seen on TV.
