"Despite being successful enough in Japan to warrant four anime seasons, The Familiar of Zero never got far off the ground in North America when it was originally released. The first season was licensed and released back in 2008 but beyond that the following seasons were never pursued. Until now that is, with Sentai Filmworks not only re-releasing the original first season but continuing into the second with The Familiar of Zero: Knight of the Twin Moons. So now that the second season has debuted in the West, is it worth continuing?"
