I actually think Half-Blood Prince was the most boring for me from memory alone, because I remember so little about it. The third was the start of the darker part of the books starting to show and it was a huge change of pace, but I didn't mind it so much. Out of the first four books, I agree that it was pretty weak for me. I'm a Goblet of Fire fanboy. That was such a good book. I remember being SO fucking upset that they cut out Quidditch. I LOVE Quidditch. 

I don't know about that. I'm kind of an asshole when I want to be, like Ron, but I'm also capable of being a good, supportive friend, like Ron. And no, you're Hermione; I can always count on you for help. You're intelligent, loyal, and I can count on you to help me solve a problem. Bear with me. I can probably do more but I'm battling drowsiness and trying not to write someone a bad post xD
