Bellatrix runs on the table right after Dumbledore is killed. She is so excited, no euphoric and that is one of her ways of celebrating I suppose.
Harry and Ginny are hugging in greeting. Harry arrives unexpectedly at the Burrow. No one there knows he is going to come and stay. THey are all completely suprised. Although they scene is completely unfaithful to the book it is rather funny. Harry's trunk and Headwig suddenly appear and, oh it is a highly visual scene, can't explain it without it losing its humor.
I Personally think it is deplorable that the writers and directors of the HP movies thought it was necessary to change so much of the last few books when I believe part of the brillance of Rowling is how easy it is to form a clear picture in your head of the scenes she writes. I have always thought the movies, especially the last two did a terrible job mainly because of Gambon and also because of the diluted belief that people would not find a movie true to the book entertaining enough.
That said I was terrified that this movie would ruin the story, we all knew already how much was going to be invented. But this is the first time I think that their invented scenes actually worked (for the most part). I actually enjoyed watching it, I was honestly expecting to cringe throughout the movie like I have in the past.
So would I have prefered them to have been true to the book? Absolutely
But the previous movies have already ruined that possiblity. To much was changed and left out for them to start being faithful to the story now.
So that all things considered this was much better than I would have thought possible.
