What's all this about an attack on the Burrow?

they added the scene (since, as it seems, there r not enough in the book for them*being sarcastic*)
yeah deatheaters attack on the burrow and harry saves ginny from them.

yes, this was not in the book but it is in the movie. It is an extra clip that they added and it is supposed to be fantastic! I think it is to show more action and more with how Harry values his friends, and that the Weasleys are like Harry's family. Also it shows Harry saving Ginny =] how cute!

well actually the death eaters came to attack the burrow in search of Harry but they also go 4 ginny cuz the death eaters know if they go 4 ginny Harry is gonna come out to save her (which he does)

Oh...i've heard of some new scene approved by Rowling in which weasleys home is violently interrupted by attacking death eaters and also some scenes including voldy. But in book voldy didn't even appear directly' did he? And the ring of fire is Dumbledore scaring off inferi after retrieving horcrux.

They were planning to lure Harry out of the Burrow where he was safe and capture him. It was not in the book, it was probably added for more action in the movie, since they left out all the fighting where Death Eaters enter Hogwarts. It's just some thing the director added, like how Harry thought he saw Voldemort at King's Cross in OotP

Idk why they added the scene but I loved it; the more Bella the better.

The film adaption of the book got really uninteresting due to all the sexual tension between the characters. So, to make the movie even more interesting, this scene was added into the movie. Yes, it was not I'm the book. It was just added to hold the attention of the viewers
