10) “Argentina” — Dexter
One of the nicest surprises on television this year was Dexter’s renaissance in quality. After some misguided years and a true nadir of a season in 2011, Dexter finally embraced a real progression in the story—having Debra find out about her brother’s “hobby”—and was all the better for it. The tension between Deb and Dexter led to some of the show’s best scenes ever. And since Dexter didn’t spend the entire season chasing his usual Big Bad Guy, Season Seven actually had decent subplots, including great guest performances from Ray Stevenson and Yvonne Strahovski. In “Argentina,” the show was even able to address the weirdest element of last season—Deb’s crush on her brother—in an impressive and compelling way.
