We already seen the boys fight witches, so mystery like is nothing new. The big thrill of the episode was to see James and Charisma back together on screen, superfun for all Buffy lovers like me. So for non Buffy fans this episode isn't that great, it has some twist and turns but I get the feeling that the writers only wanted to show off the old Buffy actors.
Fun while it lasted but I hope for some real Supernatural action in the next episode!
