I thought they should have definitly put the house elves in as well as the Quidditch World Cup (the actual match) and S.P.E.W. and finished up the Rita Skeeter plot and shown the kitchens!! That stuff was important (to me at least) and they could've cut out the dragon chase thing or something else.
I thought that they were trying to make the films as close to the books as possible, not trying to do better than them.
Now that that's out of my system...
