As for Goblet, I'm already hearing reports of fans of the books being disappointed by what was left out for the film. Hey, kids, there's just so much you can pack into one film!
OK, from what I hear we'll be missing the subplot about SPEW. And the older Weasley brothers, Charlie and Bill, won't be seen (kinda bummed on that, they've always sounded hot to me, like the older brothers I wish I'd had). This could lead to Fleur's later...oh, that's spoiler material, sorry.
But I'm pretty sure Rowling has made clear what has to be included and what can be cut. The Dursleys don't make an apperence here, but haven't they become repetitious by this point? They should be back for Order of the Phoenix, as they're much more important in that book. Peeves has never been in the films, I'm certain with Rowling's OK.
I am so looking forward to tonight.
