love love love love love Lost. my brother begged me to watch lost for years, and i thought how boring another gilligans island. then i was painting and decided to give the first season a shot. all i can say is that i watched every episode up to the 4th season within a week.
it's by far the best show ever written.
other shows i love: 30 ROCK, office, arrested development, weeds, californication, dexter, flipping out, top chef
my favorite thing to watch however is documentaries and biographies.
my newest favorite is : http://www.imdb.com/title/tt0390123/
it's about Henery Darger, an man who died in the early 70's, he was old and a janitor at a hospital for years, he was an orphan and some say mentally ill. he spent his life, when not working, in an apartment doing paintings and writing that no one ever saw until he died. this is a sad but incredible story. his work is just amazing and his story is very interesting.
