SEASON PREMIERE: A second season of this medieval musical comedy wasn’t expected by many – even by many of those making this goofy but little-viewed limited series last year. But here it is, back for Season 2, with Madalena (Mallory Jansen, pictured) on the throne, Princess Isabella (Karen David) in the dungeon, and Galavant (Joshua Sasse) paired, Defiant Ones style, with an on-the-road, in-danger King Richard (Timothy Omundson). As with Season 1, two episodes are shown back-to-back each Sunday for a month, beginning tonight.
