I would have liked to have seen something about what was going on at the school before the Trio got there. Headmaster Snape! C'mon!!
I totally agree, now that I think on it. I know the books are all from Harry's POV, but I really missed the whole school setting in the last book, especially Mr Bigman on Campus Headmaster Snape. Would've made for a much more interesting read than the Creepy Family Dumbledore and poor mushroom-hunting Hermione. Heheh! :D
