Heh, I agree regarding Harry. I spent half of OotP wanting to smack him. I'm not sure what changed (will have to re-read it) but somewhere in the middle he became likable again.

They definitely all have their flaws, but I guess that's what also makes us love them in the end.

Speaking of angry Harry, I once saw a funny icon once with a picture of Harry that said "The Caps Lock Gene ... definitely dominant". Tee hee.
