How do you cut a book in half? Vary carefully! The time flew by, you were deep in the story as one cliff-hanger after another crept up and was resolved. That method meant that you were well prepared for the final cliff-hanger that will lead you into the second film. As always, the choices about what to leave in, what to cut out and what to slightly modify to make a Harry Potter book into a movie were very well done. After all, a movie adaptation of everything in every book would take a couple of months to watch! Go see it, then go home and re-read all seven books in time for the last film so you don't miss a single detail!
By this point, if you haven't read the books, you will not have all of the master plot information, and the movies don't have the time to give you everything. It's been that way from the start and won't change now.
The challenge is to make good movies BASED on the books and this film does an excellent job of that. Some scenes and plot points have been relocated from their "by-the-book" placement, whole sub-plots are missing entirely, but the end result is good theater. J.K. Rowling's comedy gets a lot of exposure which helps diffuse the dark tone.
We'll get the DVD for the deleted scenes and will enjoy seeing this one again.
