I thought the movie was very well done compared to some prior installments of the Harry Potter series. I noticed that there were a couple of slow parts during the movie, but anyone who's read the book knows that the movie compressed a couple hundred pages of slow, yet necessary-for-the-subplot, material into a relatively short stretch of film. I did notice, as with some prior installments in the movie series, that right from the beginning of the movie, if you haven't read the book, you won't have any reference point(s) for what's going on. Additionally, I thought the acting in this movie was better than some of the prior installments. Maybe that's because the kids have grown up and have some good experience under their belts? Finally, I noticed that this movie covers the first 501 pages of the book, which leaves 258 pages (US Scholastic edition hardback) for the last movie. That suggests to me that the director (Yates) and writer (Kloves) may be planning to give great, detailed attention to the remainder of the saga, which IMHO is simply due diligence.
