I'm glad she did her own stunts - but that doesn't have anything to do with martial arts or fighting. When you throw a punch in TV land, you do NOT connect. It is kind of like when Kevin Sorbo (sp? - Hercules) was lifting in a gym and one of the guys said, "You aren't that strong!" "Darn it," Kevin replied, "Guess that means my Dad wasn't really Zeus, either!"
If martial arts aren't practiced as full-contact & competitive, then it is just a cross between ballet and wishful thinking!
