This is a really great spin-off. although it's marketed as a kid's show, i'm a teenager and i love it, as do loads of my friends, and my parents. it's exciting and fun, and a lot less violent than torchwood (but i still love that too!). but even if this series is less violent than others, that doesnt make it any less scary, nerve racking and exciting. plus, this box set has some great extras too. i'd reccomend it to absolutely everyone!
