I am going to see the next installment of Harry Potter tonight, and I am as excited as a little kid. seriously. I spent some of my week re-reading the last book in the series in preparation. I adore Harry Potter for the same reasons that I loved Lord of the Rings. A fully realized world. A serious struggle between good and evil. The temptations and pitfalls of power. Choices have consequence, for good or ill. Likable characters. People are often not all good or all bad, but the usual mix of the two.
There is a lot more to this than a simple story to entertain children. And I absolutely love it.
