Interesting but not great
This is potentially very good but something seems to have a little wrong in the way the story is developed. The science fiction and urban fantasy elements work well but there's confusion when it comes to tying in Jo's back story. The focus on young girl's bodies is also rather obvious and does little credit to the studio in pandering to the male fan base. Perhaps if the writers had thought more about getting the story right and less about how much cleavage to show, it would have been a better serial.
