10. 'Arrested Development'
Anticipating the rise of niche sitcoms like It's Always Sunny in Philadelphia, Arrested Development was never a ratings juggernaut. (It finished 120th in its first season.) But that lack of popularity only emboldened its writers, who slyly savaged the Bush administration, Orange County and Hollywood phoniness ("Marry me!"). This tale of a wealthy family rotting from the inside snagged six Emmys during its initial three-year run, including one for Outstanding Comedy Series. But its real legacy is its cast's continued ubiquity in film and on television: Bad Words, Archer, Superbad, Veep. And it's still impossible to hear "The Final Countdown" without laughing.—TIM GRIERSON
