What New or Returning Midseason Series Are You Most Looking Forward To?

It's that time of year again as the broadcast and cable networks trot out some new fare to keep us entertained these cold winter months. (Unless you live in Los Angeles, as I do, where it's once again in the 70s.)

As the networks make way over the next few weeks to unveil some shiny new programming and bring back some old favorites, I'm curious to know which new and returning midseason series are you most looking forward to?

Amid the seemingly hundreds of series slated to premiere over the next few months, can you pick out the one that excites you the most? Is it the triumphant return of Chuck this weekend? The final season of Lost? Looking forward to getting the backstory on the birth of the Cylon race on Caprica?

Or, are you more interested in catching up with Nurse Jackie? Diving into the blood-and-sex of the 300-inspired Spartacus? Or the grit of HBO's ten-episode limited series The Pacific? Or hoping that BBC and BBC America announce a start date for the Matt Smith-led Season Five of Doctor Who?

Discuss which series you're most excited about and why.
