definitely sherlock. the third season is airing this sunday (three episodes per season), but as mentioned before the episodes are 1.5 hours. totally worth it. i promise
fyi the third season is on PBS, not netflix. but dont watch the current season without watching the first two..
And if we're going beyond Netflix, Modern Family is ****ing great. Manny is a boss.
Breakout Kings is pretty cool, too. It only has two seasons, so you might be disappointed when it ends. You can say the same for Dirty Sexy Money, though.
