To put it concisely, Sanctuary is a wonderful--if somewhat unoriginal--show with positive messages about challenging the system, having an adjustable world view, and accepting everybody for who they are. The effects and atmosphere were pretty decent for TV, and the camera work was downright excellent. Acting was also top notch, and while somewhat predictable, the actors were mostly very engaging. Yes, there is quite a bit of violence, some of it rather bloody, but none of it was unduly graphic. Still, this is probably best for teens and up.
