I saw the movie over the weekend and it is hands-down the best of the films thus far. Though it did leave out a lot of details, as every film did (and nearly every book-to-film adaptation does), I didn't find it confusing in the least. I did notice specific elements of the story missing, but none that were seriously vital in the basic storytelling. Boyfriend has never read a single one of the books, has only seen the films, and English is his second language. He had no problem following the plot. He is not a Harry Potter fan, but he loved this film. We both agreed it was the most mature of all the films and the acting, direction, and screenplay were all superior. Prisoner of Azkaban would be the second best of the films. Goblet of Fire is still my favorite book, which is why I found the film disappointing.
I'm rereading Half-Blood Prince now to prepare for the final book. Personally, I've always felt Order of the Phoenix was setting us up to see Harry not only live in the end, but become the new Defense Against the Dark Arts teacher at Hogwarts after his graduation. That way, Rowling could possibly continue with a new series based on a new student (possibly a girl this time), yet keep Harry Potter and other familiar characters as peripheral characters in stories that could give a new slew of favorites.
And I always wanted Harry and Hermione to end up together. I'm not huge fan of Ron.
