I have to say: Read. Relieved.
On the whole, it works brilliantly. Of course, there's the epilogue, which has largely been reviled.
But I wouldn’t change a thing, really. It wouldn’t do for us to out-JK Rowling JK Rowling. The book began in her head, and in her hands alone can it reach completion. It’s hers to do what she will, and I for one, am satisfied.
