I'm not gonna lie when I've said that Harry Potter got me started into reading as a pre-teen. I will always appreciate J.K. Rowling for that. Always.
Having said that, when you read other books, you know that she's not the best and that her books barely touch the works of other great masters. Her narrative may be superfluously appealing, like Stieg Larsson's, but she could never reach Jane Austen's feet, for example. I don't see HP being held that high by the academia in the future.
