I also finished the book recently. Just a lil' warning to these of you wanting to read the book...
It's quite a dark and unsettling novel. I can't imagine the movie being rated less than a PG-13 rating. Maybe a R rating. I have to say that the books mature more from book to book, therefore... not all children will be prepared to face some of the contents in these books.
I have to say that it was better written than the last book though. Not that the book was bad, I really enjoyed it. But I felt that the writing skill could had been done with a firmer grip.
My mind is racing with so many thoughts from this new book, and it did confirm some of my beliefs regarding some characters and also disproved me on some too as well. Some of the details in this book will stick through your guts like a knife and twist it around.
Yet people who don't read Harry Potter novels today still think of them as children's books. They're deeply mistaken, this one isn't exactly a book that a 8 year old child should be reading. Neither was the last book, and the book before that.
Beware, read at your own risk.
