Thank the television gods for Lena Dunham, Julia Louis-Dreyfus, and Warwick Davis—and, for that matter, HBO. Without their respective new shows (Girls, Veep, and Life's Too Short), 2012 would go down as an all-around terrible year for debut TV shows. On the positive front, there's also ABC's Nashville, the only non-cable rookie series that made the cut on our list of The 25 Best TV Shows of 2012. Otherwise, the various networks, by and large, failed to produce titles worth caring about.

As you'll see on the following countdown of The 25 Worst TV Shows of 2012, a few returning chumps are surrounded by a plethora of embarrassing newcomers, some of which were promptly cancelled and a few that won't stop plaguing the airwaves anytime soon. For your sakes, we pray that you're unfamiliar with most of these shows—if so, you missed the nightmares before they disappeared from all TV listings.
