A hurricane can postpone the Firewall & Iceberg Podcast, but Sandy couldn't stop it forever. After I spent the last week either powerless or as a nomad in the wilds of Connecticut, I was finally able to return home last night. In fact, the podcast was supposed to be finished yesterday, but midway through recording it, I got the call that our power was back on, and had to hastily pack up the family truckster for the drive home to Jersey, so we're technically reviewing HBO's excellent "Witness" a day late. That's what On Demand and HBO multiplex channels are for. In addition, Dan and I review TBS' "Wedding Band," discuss NBC's mid-season schedule, the "Up All Night" format change, how we feel about "Nahville" and "Last Resort" these days, and the latest episodes of "The Walking Dead" and "Homeland."
