With OK ratings and a big financial commitment by Syfy, the network’s new video game-tied drama Defiance is likely to get a second season. But if/when it does, it will be without executive producer Michael Taylor. Taylor was one of three writing executive producers on the first season, which has been completed, along with showrunner Kevin Murphy and Rockne O’Bannon. He won’t be returning for Season 2. Taylor is a sci-fi veteran who worked on Star Trek: Voyager and Deep Space Nine. He has a long history with Syfy, having served as co-executive producer on hit Battlestar Galactica and spinoff Caprica.
