Soooooooo, getting back on track... I'm curious if anyone else expected or hoped that other nations' magical societies would play a larger role in the seven-year-story? As I recall, when
Deathly Hallows came out, there was a fair amount of grumbling about the extended camping trip that made up a fair amount of the book's narrative and page count. Would anyone else here have preferred a visit to Beauxbatons and/or Dumstrang, or somewhere else, than what we got? Offhand, I can't think of
any important new location the last two Years (books
or movies) introduced other than the horcrux zombie cave and the grave of Harry's parents, and I'm not sure the latter even qualifies as "important."
As for the location of the final battle... I'm of two minds. On the one hand, I can't help feeling that having it be in Hogwarts was a boring and lazy choice that prevented the overall story from being an epic, because an epic fundamentally involves a long journey to a far-off place, with Mount Doom and the third Death Star being classic examples. What's more, having the ultimate battle of good vs. evil be decided at a children's school feels just plain silly. That said, Hogwarts
is the center of the overall story, so I'm not sure where
else it could have taken place. (Certainly not the dull and underwhelming underground Ministry of Magic!)
Maybe if the last year or two had built up to Voldy reclaiming, say, the hidden/lost castle of Camelot as the final step in his grand plan, that could have made a fitting site. Heck, doing so could have paid off the in-universe introduction of the historical wizard Merlin, from Harry's first train ride to Hogwarts.
