I've only seen a few episodes and it starts off slow for just about a half of an episode and starts moving pretty good. There are a few ideas we've seen before but like anime that's at least decent, it tells it's own story.

The fans at ANN seem to think it's only worth a 6.5 . . . I think it's better that that . . . . So barring a "Mai-Hime" type of ending or a plot malfunction, it gets a tentative 7.5 from me.
