This week: Former DC and Marvel Comics editor Bob Greenberger brings us up to speed on Batman and discusses his awesome Essential Batman Encyclopedia. We get our a capella geek on with The Blanks (a.k.a. Ted’s Band from Scrubs). And we talk V, sharing our thoughts about the new remake. In the news: Dollhouse’s cancellation (and possible Dr. Horrible news?), Avatar’s half-a-billion-dollar budget (and killer story), and Modern Warfare 2’s $300 million opening day.
