I have been missing American TV. I wasn't an addict or anything but I did have my favorite shows. My couch potato hours were immediately replaced by hours in front of the computer because of the lack of American sitcoms on Korean TV. (Note to self...really should get a more comfortable chair for the computer desk.)
I love watching the Amazing Race. I really got into Heroes before I left the States. I haven't seen an episode of the Simpsons or Monk in months!
Korean cable offers a wide array of choices. There is always at least one movie on in English. There are Korean talk shows, comedy sketches, and drama series. National Geographic and Discovery air shows but they are all dubbed over in Korean. There is always a football (soccer) game on with Korean players or any number of European league games. Always with Korean commentating though. For English speakers there is relatively a small selection. (However, it is a huge selection if you consider the Korean programming offered in the States.)
