Might be good to avoid watching general television but I have a few favourite shows nevertheless and most of it is HBO.
Game of Thrones is the best fantasy in a long time! Like Tolkien for adults. Who doesn't like war, love and politics in middle earth:ish setting? :)
The Wire might be the best drama show on television ever. Humor shows I really like are Curb your enthusiasm (better than Seinfeld ever was) and the quite different Arrested development.
Action or horror film are generally not for me so instead I go for good drama in all its forms. A few I like: Todo sobre mi madre, Volver, Weekend, Brokeback mountain, The ghost writer, Carnage. Try to watch as much spanish stuff with subtitles as possible. It's such a pleasant way to keep the language up to date! (next best thing to conversation) Enjoying a movie and at the same time picking up a few new words.
Old classics: The big lebowski, Blade runner, 2001, Solyaris. Favourite romantic film: Lost in translation (no contest), it is perfect!
An omnivore when it comes to food, I enjoy new things in general. A good new beer is always welcome!
