I have followed the craze! Two days ago I read HP&tDH and it was fantastic. J.K. Rowling can't be human. I won't write much just because so many others will. I will just suffice in saying this:
Harry Potter cannot be your favorite book. It's in an entire league of it's own. If you ask someone "What's your favorite book" and they answer "Harry Potter" you have to ask them again "What's your other favorite book?" Because Harry Potter is just so good.
One of the reasons Harry Potter is so good is it's length. I know more than one person who groans and says "I can't read it, it's so long!" But have you noticed that since it's so long you can think about it as you read it. You can solve the mysteries, or at least try to. Whereas in shorter books often they're over before you have time to think.
Well that's my Harry Potter say so. I could go on forever but I won't.
