SERIES PREMIERE: Refreshingly, this new series from Sundance, hosted by Jim Rash and focusing each week TV writers from a different current series, is more informed discussion than fan fest. Where, say, AMC’s The Talking Dead feels more like a small-screen Comic-Con, this show is hosted by Community actor Jim Rash, who won an Oscar for writing The Descendants. Jess Cagle from Entertainment Weekly comes in at the end with a few final questions, but Rash holds court nicely throughout. The only complaint is that this discussion – tonight’s opener features Breaking Bad creator Vince Gilligan, the writing team and star Bryan Cranston – takes place on a mockup set, rather than on location in each show’s real writing rooms. Why not visit these writers in their natural habitat, which would, in and of itself, say a lot?
