Aww noo...
I'm with Vivisteiner on this one.
As I was reading it, I thought, surely they can cut out a lot of this and manage to squeeze it into four hours. I hope they give it a go.
I hate movies in two halves. I guess Matrix Reloaded/Revolutions ruined it for me. Though I think Kill Bill was perfectly acceptable.
EDIT: Half Blood Prince, November... I think.
