I've never seen any of the Harry Potter movies either. I don't think I'm the target audience, which seems to be teens, but correct me if I'm wrong. The closest I've come to that science fiction/fantasy genre is reading "The Mists of Avalon" by Marion Zimmer Bradley, along with the prequels "The Forest House" and Priestess of Avalon." However, "Mists" the better of all these books.
