Discovered by other supernatural beings (called the Fae), Bo is drawn into a world wherein everyone must choose a side (light or dark) and nothing is as it seems. My wife said the idea of Canadian Fae running about is very similar to Canadian fantasy author Charles De LInt's Newcastle series of books, and the series definitely plays up the humour to match its dark premise (it turns out that Bo is a succubus, and that both groups of the Fae may want her dead), in introducing a side-kick character for Bo, a young girl named Kenzie who is both quite brave and a little stupid (a great mix, by the way).
I would consider the series Urban Fantasy, and although the subject matter means it is not for younger audiences, I think that older teens would probably find the show a lot of fun. The cheese factor is pretty high, but finding a good balance between humour and dramatic tension can definitely win a show over for me.
Overall, the pilot was fun, I think we'll be watching the series from now on (unless it goes horribly wrong), and I'm quite interested to see where they are going to go with this intriguing characters throughout the season.
