You can also catch the 2nd season in iTunes, IIRC. I've been a long time fan. Even read some of the comics before it was announced it would be a tv show.

For those just coming into the show during this mid season hiatus, there is a live show that airs right after each new episodes called, The Talking Dead. Its a 30 minute show that reviews the new episode and they usually have one of the shows actors, fx guys, producer or writer on. I dig that kind of stuff.
