Although we know that it was editorially necessary to leave out some characters and events from the H.P. books when the movies were made, what is the one character/event that you would choose to add back in to the movies if you could? And the reverse: what movie element not present in the books would you add to the books if you could?

Personally, I really miss Peeves in the movies. The dance between Harry and Hermione in DH part 1, however, was genius!
