But I felt that... well, to Rowling different details were important than they would have been to me. To me, things like - 1/4th of a population cannot be evil!; House reconciliation; Snape's life debt; Unforgivables are evil! - these pieces were the important ones. To her, it was that Harry's Quidditch team should be present in the final battle...

I hope you don't mind me butting in to say thank you and I think this is very well-put! I've been trying to sort out my own reactions to book 7, and you've put something into words that has been nudging around the edges of my brain.
