I thought it was excellent.
I agree that it wasnt perfect (what book is?), and there were some flaws (like people have mentioned, such as the slow bits, and the deathly hallows only being introduced past halfway through the book stood out to me), but they were only small things.
I dont judge a book (or anything) simply on its failings or its sucesses. I look at it as a whole.
And since I couldnt put the book down from the moment I picked it up, I would call it an excellent read. I think it was a fitting conclusion to a wonderful series.
As for the epilogue, I didnt mind it. You have to remember, that first and foremost it is a childrens story. That doesnt mean adults cant read it, or that it doesnt have adult themes etc. All im saying is that it is primarily written as a childrens story, and the epilogue would have satisfied most of the kids. I remember when I read books as a kid I was always curious to know what happened to the characters after their adventures were over, wanting to know that the future was bright and that everything would turn out fine. The epilogue was definitely aimed at the younger readers who need that sense of closure.
As for us adults, we can choose to ignore it.
I agree that the style of the epilogue did seem a little rushed and not up to the standard of the rest of the book, but i think that was intentional. It made it feel brief and vague, as if to make it so that you couldnt dwell on the moment too long, but just long enough to know that 'all is well'. What was happening itself wasnt important, but the fact that everything turned out fine is what mattered.
Just one question though. I remember JK saying that in the book a non magical person would perform magic. Who was it and when? Did I miss something?
