Harry Potter made his first appearance in 1997. J.K. Rowling's last book was finished in 2007. Now the last of eight movies has opened, The Deathly Hallows, Part II. "In the cottage industry of Potter analysis, no superlative is too super, no grandiosity is too grand, no pie in the sky is too high." That's according to Monica Hesse of the Washington Post, who's read all the books and seen all the movies.
