Query: He's back!

I will need to re-read this book because I know I read it so fast that I must have missed things. However, Harry does it again!Harry and company are growing up and it shows. Rowling captures the mercurial quality of Harry's emotions perfectly. How can anyone expect Harry to be perfectly civil all the time given what he has been through? There are plenty of foes this time around. Not just people, but, the emotional battles Harry must go through.Rowling sets the stage perfectly for the next books. She is clearly letting everyone know that she means business from here on out. To that end, this book was not *nearly* long enough.I don't understand why people are upset with the "dark" tones. Disney films are loaded with dark currents and imagery (not to mention, death).At any rate, it was a pleasure to be back in Rowling's world.
