Great video, short, yes, but every video with the lovely Dan in it is great in my opinion, no matter how short it is.
I'm happy and sad the films are being split, there is just too much in the book to leave out in the movies so spliting them would give them more to work with. I'm upset that we will be seeing one part one year and then have to wait until the following year to watch the rest of it, but it just means that Harry Potter is going to go on longer than what we thought it would. Can't wait for both HBP and DH to come out!
