48. 'The Office (U.S.)'
Nobody expected this to be more than yet another example of a U.S. network trying to rip off an edgy Brit-com and getting it all wrong. Except, with Steve Carell as the world's worst boss, it turned out to be a groundbreaking and original comedy in its own right, with a dream team of eccentric employees lost in the cubicles of Dunder-Mifflin. It was looser, riskier and more ambitious than the U.K. version, not to mention warmer – Carell's Michael Scott wasn't hateful, just a moron – with a cast including Rainn Wilson's Dwight ("Through concentration, I can raise and lower my cholesterol at will"), Mindy Kaling's Kelly and the ever-bilious Creed Bratton. (Let's just pretend those last two post-Carell seasons never happened, OK?)
