I'd make an adjustment. Harry Potter is decent fare for kids and teens. If you're a huge fan and an adult, well, I don't know what to tell you really.
Its seems to be fairly popular with the house frau too. At least the ones who have kids, teens or grandkids who are into it. With the exception of my wife, all the women in my family are into Harry Potter to some degree.
