Yeah, it satisfied me. The ending told me what was important; that life went on, the shadow had passed from the land, and a new generation would carry on the traditions that our heroes fought so hard to preserve, etc, etc.

Given that almost anything Rowling actually resolved for certain was going to leave at least some segment of her fans upset, why make concrete anything that isn't especially important to you? Leave the holes for the ficcers to enjoy. :)

It worked for me. When I closed the book, I thought "Yes, that's good. I approve of it."
