I watched the original, tried hard to follow the story and make sense of it. I was interested enough to watch the second season. It was a horrible letdown. The characters you know and love have lost their charisma and wittiness from the first season. Not to mention that the cover character for the show loses his value and impressiveness for most of the show.
The story is focused on a character completely unrelated to the first season. Honestly, it makes me think they just didn't care about continuity, and simply made up a story to use up the advertising budget they had for this show.
After about three episodes, you'll grow tired of the magic girl transformation sequence that haunts every episode, and the general non-sense of the plot.
Supremely disappointing addition to an otherwise interesting series. Had to knock it down almost entirely on the plot/characters.
overall score: 1/10
