Sorry, I know you don't want to hear pedantic corrections from some random anonymous lurking the internet, but actually, Dobby's last words were not "Dobby is free". That really wouldn't make sense, even, as Dobby was freed in the second book. IIRC, his last words were "Harry Potter".

Also, did you miss the Ron/Hermione sucking-face scene? Not trying to be an ass, just asking.

Everything else has already been mentioned. Needless to say, I don't agree with your interpretation of the books in the slightest.
