For the sake of general discussion, as I'm very much behind, I enjoyed "Deathly Hallows", it ranks as being among my favorites from the books, which include "Stone", "Prisoner of Azkaban" and "Half-Blood Prince" (even though I thought Rowling, a competent writer, did a really poor job with the Harry/Ginny romance).
As for the Order of the Phoenix film, well, it was better than I thought it would be, and I'm saying that as someone who is generally cold hearted towards the films.
I'm wary though for how "Half-Blood Prince" will be put on screen.
