SEASON PREMIERE: This series moves to the CMT network beginning tonight with a two-hour season premiere, under the auspices of new executive producers Marshall Herskovitz and Ed Zwick. They’re the team behind thirtysomething, and My So-Called Life, so expect the new Nashville to be especially keen on exploring character, and smaller moments. It will, however, wrap up all of the big plots left over from the old ABC series, starting with the plane crash threatening the life of Juliette (Hayden Panettiere) – and her future on this series.
