What Is Your Favorite Show of the Year?

Lost
As we head into the final days of the year, we've begun reflecting on the past year of television with one question in mind: Which show was your favorite in 2009?
Were you happily bewildered by Lost's time-tripping fifth season? Did comedies such as How I Met Your Mother and The Office make you laugh harder than ever? Did new series like NCIS: Los Angeles and The Vampire Diaries earn a spot in your weekly TV lineup? Did cable dramas like Sons of Anarchy and Dexter keep you riveted?
As you think back on these and many other worthy shows (Battlestar Galactica already seems so far away), we want to know: What is your favorite TV show of 2009?
