Midseason TV 2012: Previews Of 'American Idol,' '30 Rock,' 'Bachelor' And More Returning Shows (PHOTOS)

It's the second most wonderful time of the year for TV fans: Midseason premieres! The networks are rolling out new offerings to replace failed new shows, sometimes with even newer shows, other times with old favorites that have been gone for far too long. We're talking to you, "30 Rock" and "Mad Men."

Besides Liz Lemon and Don Draper's returns, there are new seasons of reality offerings like "American Idol" and "The Bachelor" and critical darlings like, "Cougar Town" (we hope) and "Southland."

What's Liz been up to since last May? Who's that elder cougar going after the new "Bachelor" Ben Flajnik? Find out the answers to those questions and many more below.
