Okay Mauler, just for you. Or the masses. So no one whines about it being ruined, if they even care, here is a subtle reminder there are plot spoilers coming:
SPOILERS
The more major characters who die are Mad Eye, Lupin, Fred Weasley and Snape. Oh, let's not forget Voldemort. As for minor one's there are a few, Dobby, Tonks, Bellatrix and Crabbe come to mind but there may have been a couple more.
END SPOILERS
That's the long and short of it, and yeah my inner nerd did come out for it...I've liked Harry Potter since I was much younger.
