The FX drama delivered an electrifying sophomore season and one of TV's best baddies: redneck matriarch and moonshine poisoner Mags Bennett (Margo Martindale). But the complicated relationship between U.S. Marshal Raylan Givens (Timothy Olyphant) and his villainous former best friend Boyd Crowder (Walton Goggins) remains the most compelling part of this outstanding series for me. That gets even thornier in Season 3, which begins Jan. 17.
Rest of the Top 15 (in no particular order): "Wilfred" on FX; "Community" on NBC; "Game of Thrones" on HBO; "The Walking Dead" on AMC; "Doctor Who" on BBC America; "Spartacus: Gods of the Arena" on Starz; "Strike Back" on Cinemax; "Sons of Anarchy" on FX; "Fringe" on Fox; "Raising Hope" on Fox; "Shameless" on Showtime; "Boss" on Starz; "It's Always Sunny in Philadelphia" on FX; "Downton Abbey" on PBS."
