Well, i've never had anything against them adding scenes, so far i've liked all the scenes they've added. That's why i'm very much looking forward to this too In the book the atmosphere and everything that's going on are described carefully, but in the film they have to change or add things to be able to tell the story. As long as they don't cut out anything crucial, i'm ok with the added scenes.
And Ron/Hermione scenes are always welcome <3
