Critical reception for the first season was overall negative. It was heavily criticized for it's campy tone, poor animation, several inconsistencies in each episodes and nearly predictable story lines. Because of it's terrible results, the show was forced to be produced under a new studio (Season 2). Though it was slightly praised for being reliable to the source material. For Season 2, the reception became more positive because of it's darker tone. But the ratings continued to drop after suffering from the first season's outcome, thus cancelling the series.
